The Most Common 2.0 D-ID Mitsubishi BSY Engine Problems

The BSY engine is an in-line 4-cylinder engine with a displacement of 2.0 liters. The maximum power of the engine is 140 hp. Diesel fuel is used to run the engine. The fuel is supplied by direct injection.

This ICE was developed by the Japanese company Mitsubishi. Soon after the release of the engine, some American companies, including Chrysler, became interested in it.

On many cars of this automaker you can find aspirated BSY and its turbocharged version.

Reliability and Advantages of the BSY engine

One of the most important advantages of the BSY engine is its low fuel consumption. When using a high-quality diesel engine, this indicator in the combined cycle will be 6.6 – 6.7 liters per 100 km.

It should also be noted the good level of environmental friendliness of this engine. Emissions from its work are approximately 177 grams of carbon dioxide per 1 km of run.

Disadvantages and problems of the BSY engine

Most Japanese diesel engines have similar problems. Among the most serious “pain points” of the BSY engine, motorists distinguish the following characteristics:

  1. Maslozhor. This problem occurs even on small runs. Therefore, the car owner must regularly check its quantity. Otherwise, the level will drop and the engine may seize.
  2. Toothed timing belt. The service life of such a device is only 70-90 thousand km. If you do not replace it in time, it may break, and this, in turn, will lead to the valves bending and a rather expensive repair.

Applicability of BSY Engine

  • Chrysler : Caliber (2005-2011)
  • Mitsubishi : Grandis (2003-2011), Outlander (2005-2009)

 BSY Engine Prospects for tuning

As you know, diesel engines are not very amenable to all sorts of modifications. To add some extra horsepower to this engine, experts recommend installing a sports direct-flow exhaust system. You will also need a competent setting of “brains”.

And the easiest solution would be to change the atmospheric version of the internal combustion engine to a turbocharged one, where there are more options for increasing power.
