4E-FE Engine Toyota 1.3 EFI Specs, Problems And Reliability

The 1.3-liter 4E-FE gasoline was produced by Toyota between 1989 and 2001 and was installed on many cars. But it is known mainly from the Corolla model .

The production of the engine began in 1989. The 4E-FE engine has gone through 2 restylings. One happened in 1994. Then they increased the diameter of the cylinders, but the power dropped to 74 hp. With. (until 1996 it was 88 hp). Then, in 1997, the 3rd generation of the engine was released, developing a maximum power of 82-85 hp. With.

4E-FE is a four-stroke gasoline engine equipped with an electronic injection system controller – the so-called ESUVT. The cylinders are arranged in a row, the pistons rotate one common crankshaft. Two camshafts are used, they have an upper location in the cylinder head.

4E-FE Engine Performance Summary

Here, we will investigate the characteristics of this engine by referring to the data of the 4E-FE type naturally aspirated engine installed in Toyota’s EL41 type Corolla II Windy 1993/08 model.

Toyota’s EL41 type Corolla II
Vehicle model	E-EL41 type
Car name & grade	Corolla II Windy
Engine model	4E-FE
type	In-line 4-cylinder
Displacement	1331cc
Inner diameter × stroke	74.0mm × 77.4mm
Bore stroke ratio	1.05
Single cylinder volume	332.9cc
Compression ratio	9.6
Intake method	Naturally aspirated
use fuel	Regular gasoline
Maximum output	97PS/6400rpm
Maximum torque	11.5kgm/5200rpm

First of all, as a basic structure, the 4E type engine is a long stroke type engine with a bore (inner diameter) of 74.0 mm, a stroke (stroke) of 77.4 mm, and a bore stroke ratio of 1.05 (the stroke amount is larger than the piston diameter).

When the displacement and the number of cylinders are the same, the engine has better torque characteristics in the low rpm range than the short stroke type and is easy to handle, but in the high rpm range, the filling efficiency deteriorates and the sliding resistance increases. There is a concern that the output will drop.

Moreover, when the number of revolutions is the same, the average piston speed tends to be higher than that of the short stroke type, so the load on the engine tends to be heavier.

Among the models registered on this site, the oldest model equipped with the 4E-FE type naturally inhaled engine is the 3rd generation Corolla II [EL41 type | 1993/08] released from 1990/09, which is the newest . The model is the 5th generation Starlet [EP91 type | 1998/10] released from 1996/01 , and 30 models of NA cars and 0 models of turbo / SC cars are registered.

Evaluation from the viewpoint of transient characteristics and liter equivalent horsepower

Image of engine performance curve
Changes in horsepower	83.5PS → 97PS
Transition of torque	11.5kgm → 10.9kgm
Liter horsepower	72.88PS / L
Liter torque	8.6kgm/L

The corolla II in-line 4-cylinder 1331cc engine with a compression ratio of 9.6 and regular gasoline specifications, which is the reference vehicle for this time, produces a maximum output of 97 horsepower at 6400 rpm and a maximum torque of 11.5 kgm at 6400 rpm.

If you know the horsepower and the number of revolutions, you can know the torque, and if you know the torque and the number of revolutions, you can know the horsepower. The torque at 6400 rpm is 10.9kgm.

The horsepower per liter of displacement is 72.88PS / L and the torque is 8.6kgm / L, and the horsepower per cylinder (single cylinder volume 332.9cc) is 24.2PS and the torque is 2.9kgm.

When the 4E type naturally aspirated engine is applied to a 10-step evaluation based on the deviation value aggregated from all NA vehicles registered on this site, the evaluation is ” standard ” with a converted horsepower of [ 6 ] and a converted torque of [ 3 ]. It is categorized as ” engine with typical output (upper middle) “.

By the way, among the 4E-FE type turbo / SC engine equipped models, the maximum output was 97PS / 11.5kgm of EL41 type Corolla II, and the smallest was 82PS / 11.8kgm of EP95 type Starlet increase.

Displacement increase, compression ratio increase, bore stroke ratio change

There are three factors that determine the engine displacement: the number of cylinders, the bore diameter, and the stroke amount. By increasing or decreasing these, engines with various displacements are created.

Here, regardless of whether it is actually possible, the displacement when the piston diameter is expanded from the genuine 74.0 mm to 77.0 mm in 0.5 mm increments and when the stroke is extended from the genuine 77.4 mm to 82.4 mm in 1 mm increments. And, the change of the compression ratio when it is assumed that the volume of the combustion chamber does not change is listed.

* It is easy to say stroke up, but if you want to make a long stroke, you need a crankshaft and a compatible connecting rod, and if you can not divert it, you have to make it in one-off, so it is expensive anyway. It is a menu that requires considerable preparedness to put out.

Regarding the compression ratio, in most cases, the uneven capacity of the top surface of the piston changes as the diameter of the piston increases, so the compression ratio values ​​in the list do not match, but the displacement. Please enjoy the atmosphere that the compression ratio will naturally increase as you increase the size.

B / S ratio is an abbreviation for bore stroke ratio, and as the bore diameter is widened, the characteristics of the long stroke type, square type, or short stroke type are approached. In the case of 4E type engine, the ratio changes from 1.05 to 1.01 when the bore is increased by +3.0mm from the genuine piston.

Increased displacement with engines with similar piston diameters

There are 28 engines with pistons that are close in size to the piston diameter of 74.0 mm of the 4E type engine, so as a side note, let’s calculate the displacement when the piston is diverted and the bore is raised.

Engines with similar piston diameters are Mitsubishi: 6G71 type 1998cc 74.7mm mounted on F11A type Diamante, Toyota: 1NZ type 1496cc 75.0mm mounted on NZE127 type Prius, Toyota: GXE10 type Mark II 1G type 1988cc 75.0mm, Honda: D15B type 1493cc 75.0mm mounted on EK3 type Civic, Honda: D16A type 1590cc 75.0mm mounted on EJ4 type CR-X Delsol, Suzuki: mounted on GD31S type Cartas G16A type 1590cc 75.0mm etc. is applicable.

(Although the number of people who find pleasure in such a quest has decreased) No matter how close the diameter is, there are factors such as the diameter of the piston pin, the height of the piston, and the convenience of valve recess, so if possible, the same manufacturer, If possible, if you choose the same fuel and the same intake method, and if possible, the one with a similar displacement, the possibility of genuine diversion may increase.

Average piston speed

Next, let’s look at the average piston speed. The average piston speed at 6400 rpm, where an engine with a stroke of 77.4 mm produces maximum output, is 16.5 m / s , which is a piston speed that travels a distance of 16.5 meters per second (59.4 km / h at speed). It means that is moving up and down.

The average speed is 13.4 m / s at 5200 rpm, which generates the maximum torque, and 17.8 m / s when 6900 rpm, which is 500 rpm higher than the 6400 rpm where the maximum output is generated, is assumed to be the rev limit.

For reference, I calculated the change in piston speed when a 4E engine with a stroke of 77.4 mm is rotated up to 10000 rpm. Looking at this, it seems that the speed increases by approximately 5.15 m / s as the number of revolutions increases by 2000 revolutions.

Considering only 20.0 m / s, which is a guideline for general engines assuming mass production, it is mechanical to set the upper limit of high rpm to about 7750 rpm (whether it rotates or not). It seems to be preferred both mentally.

List of modifications 4E-FE

The E series includes the following engine options:

• Atmospheric variant 4E-FE;
• 5E-FE – engine with increased displacement;
• 5E-FHE – an early modification that was equipped with a geometry change system and a high redline;
• 4E-FTE – turbo version, the classic engine of the Starlet GT car.

In addition, it is customary to distinguish between 4E-FE generations:

List of car models in which 4E-FE was installed

The engine was produced in 3 generations, it was installed on various Toyota models:

• Starlet P80, P90 hatchbacks 4th and 5th generation;
• Corolla E100 / 110 7th and 8th generation station wagon and sedan;
• Corsa L40, L50 restyled 4th generation sedan;

• Sprinter E100, E110 7th and 8th generation sedans;
• Tercel L40, L50 4th and 5th generation sedans and hatchbacks.

Overview of faults 4E-FE

Here are some common problems:

1. The engine may suddenly stall while driving. In this case, you need to slow down, taking the car to a safe place. Then try to start the engine again. The main reason for this malfunction is the fuel pump does not have time to provide the required pressure in the line. Therefore, restarting is often successful. You can check the fuel pump for a problem like this: unscrew any fuel system hose right in the parking lot. If there is no pressure, then the pump or valve on the injector rail is faulty. It is also possible that there is a gas leak and air has entered the system;
2. Overheating is also not uncommon for this engine. First of all, you need to look at the TOZH index. In addition, overheating is signaled by such signs as loss of traction and a slight metallic knock;
3. Zhor oil – a common thing on engines with high mileage. The oil burns in the engine cylinders, as evidenced by the white exhaust. The problem is solved by replacing the valve stem seals;
4. ICE tripping occurs due to burnout of the exhaust valve. It is necessary to remove the cylinder head, find and replace the problematic valve, and grind the rest, the workers. Put a new gasket, assemble on new bolts, measure the compression.

4E-FE Engine Fault codes

They are read by the number of flashes of the Check Engine indicator. The outputs of the DLC1 or DLC3 connectors must be forcibly closed in order for the system to report a particular problem in the cipher alphabet. If the engine is running normally, the indicator flashes at intervals of 0.25 seconds. In case of malfunctions, it starts flashing much more often, with pauses of 4-5 seconds.

Service Schedule 4E-FE

Maintenance of the 4E-FE engine is quite simple – a service check is recommended every 10 thousand kilometers. During this period, an oil change is required andfilter. If the car is operated in difficult conditions, and a lot of load falls on the engine, it is recommended to reduce the service interval to 8 thousand kilometers.

Detailed maintenance regulations are given in the table:

The maintenance schedule says which oil is suitable for the 4E-FE engine. The manufacturer recommends pouring multigrade oil with SAE viscosity:

• in summer 15W/40, 10W/30, 10W/40 or 20W/50;
• in winter 5W/40, 10W/40.

Oil change in 4E-FE. The manufacturer recommends pouring oils with a viscosity according to SAE 15W / 40, 10W / 30 or 10W / 40

4E-FE tuning options

The 4E-FE engine is often rebuilt by tuners who are trying in every possible way to increase its power characteristics. Below is information about the differences between the engine and its analogues, which you should pay attention to during the modernization:

Conclusion

Toyota can be thanked for creating engines “for people” , tk. their internal combustion engines, incl. and the 4E engine, are distinguished by reasonable and simple ideas and the same implementation.

No frills and incomprehensible additions, only practicality, reliability and a decent resource. Ordinary motorists are quite satisfied with such characteristics of engines.
