Different Face of Diesel Engines

Diesel cars have long been a part of the Indian car industry. Many cars manufacturers are using diesel in variety of their car models since centuries. Some of the car manufacturers like Honda have always ignored the advantages of diesel because of the terrible clattering, vibrations and disturbances produced by diesel cars.

Diesel engine has substantial components to support effective operation and performance. Conversion of fuel into power is mainly done using compressed air at high temperature and pressure. Such engines are classified into different categories depending on how efficiently they convert fuel energy into kinetic energy in cars.
Let’s have a look on the most common types of diesel engines used in Indian cars:

bullet DI-turbo Charged

This is the direct injection turbo charged engine that is found in Mahindra Scorpio and Skoda Octavia. Direct engines used to produce lot of emissions and thus a turbocharger was fitted to the existing diesel engine. A turbocharged engine helps in increasing the performance of direct injection engines by dramatically increasing the amount of fuel combusted in the cylinder. The only drawback of this engine is that it has a lower compression rate.

bullet Naturally Aspirated

This type of engine is an indirect injection engine without any turbocharger, the one that is found in Toyota Qualis and Fiat Palio (diesel). Cars with these engines usually pull air through an air filter that is further passed through a meter. This meter then monitors and regulates the amount of air entering the engine’s combustion chambers. Naturally aspirated engines produce less power but are cheaper than turbocharged engines.

 

 


bullet CRDI

CRDI (common rail direct injection) is a modern variant of the direct injection engine. This high performance engine, found in Hyundai Accent delivers high power and enhanced mileage. This engine requires careful installation and good insulation or else it will produce vibrations that can even blow up the engine causing irreparable harm. This is a good choice for city drivers and not for long trips.

bullet Indirect Injection

In this type of engine, the fuel is delivered to a pre-chamber and then to the main combustion chamber. In the pre-chamber the combustion process begins and after spreading to the main chamber, the fuel is supported by turbulence. This yields a smoother and quieter ride. This kind of engine is found in many Indian cars like Tata Indica (diesel), Zen (diesel), Maruti Esteem (diesel), and Ford Ikon (diesel). The greatest drawbacks of this engine are reduction in engine efficiency and production of high level emissions.
