How can we increase thermal efficiency of diesel engine?

As a result, thermal efficiency was improved owing to the combined increase in injection pressure, advanced injection timing, and split-main injection. According to the analysis of heat balance, a larger amount of the second part of the main injection decreased the cooling loss and increased the exhaust loss.

How do you increase the thermal efficiency of an engine?

Lower compression ratios need higher degrees of constant volume to improve the thermal efficiency by cooling loss reductions. Therefore, a method that reduces cooling loss without lowering the degree of constant volume will be effective to improve the thermal efficiency of internal combustion engines.

What is the thermal efficiency of a diesel engine?

A typical diesel automotive engine operates at around 30% to 35% of thermal efficiency. About 65-70% is rejected as waste heat without being converted into useful work, i.e. work delivered to wheels. In general, engines using the Diesel cycle are usually more efficient, than engines using the Otto cycle.

How can I make my diesel last longer?

Diesel fuel can only be stored from 6 to 12 months on average — sometimes longer under the best conditions.



Generally, to prolong the life of the quality of stored diesel fuel, it should be:

  1. Kept cool at around 70 degrees Fahrenheit;
  2. Treated with biocides and stabilizers.
  3. Maintained properly in accordance with NFPA 110.

Why diesel engine has higher thermal efficiency?

High Oxygen to Fuel Ratio



The second reason that diesel engines have a higher thermal efficiency than gasoline engines is that of the oxygen to fuel ratio. The greater the amount of air in an air-to-fuel ratio, the cleaner the fuel burns and the more energy it produces.

What if petrol is used in diesel engine?

Putting petrol in a diesel car can cause serious damage to the fuel injection system and engine. … When petrol is added to diesel it reduces its lubrication properties, which can damage the fuel pump through metal-to-metal contact and create metal particles causing significant damage to the rest of the fuel system.
