Hydrogen Combustion Engine

Step 1:

Hydrogen is injected in the aspirated air during the intake stroke.

Step 2:

During the compression stroke Hydrogen mixes into a homogeneous mix.

Step3:

A small amount of diesel pilot fuel is injected into the combustion chamber just before top dead centre.

Step 4:

Diesel auto-ignites due to the high temperature and pressure and co-combusts with all the hydrogen, forcing the piston down during the power stroke.

Step 5:

The cylinder is cleaned during the exhaust stroke. Due to hydrogen co-combustion, the NOx and CO2 emissions have strongly reduced in the exhaust gases.
