👉 Microcombustion, also known as high-pressure combustion, is a process in which the fuel-air mixture is ignited under extremely low pressure and rapidly. This process results in a significant reduction of NOx (nitrogen oxides) emissions from vehicles. In microcombustion engines, only a small fraction of the air enters the combustion chamber, typically less than 10% of the total air intake volume. The remaining air is compressed to very low pressure, typically around 50 k
