Fuel, 2021 Mixing, ignition and combustion behavior in a rapid compression and expansion machine operated under Premixed Charge Compression Ignition (PCCI) relevant conditions are investigated by combined passive optical and laser-optical high-speed diagnostics. The PCCI concept is realized using a split injection schedule consisting of a long base load injection

Spark assisted premixed charge compression ignition engine prototype development
Fuel Processing Technology, 2016 Abstract Thermal efficiency of compression ignition (CI) engine is higher than spark ignition (SI) engine however heterogeneous fuel-air mixing in CI engine leads to higher NOx and soot formation. Fuel quality is deteriorating with time because of availability of heavier crude reserves.

Fuel Ignitability and Compression Ratio Dependence of a Premixed Charge Compression Ignition Engine
The proceedings of the JSME annual meeting, 2004 Decreasing the compression ratio improves thermal efficiency in a premixed charge compression ignition engine for the range of investigated octane numbers up to the limit of stable ignition. This is because improvement in the degree of constant volume combustion and decreased cooling loss as the ignition timing approached TDC outweigh reductions in ...
