We review developments in the understanding of cycle–to–cycle variability in internal
combustion engines, with a focus on spark-ignited and premixed combustion conditions …

The global economy and modern societies are heavily dependent on the availability of
reliable transportation systems. Reciprocating internal combustion engines are the primary …

To investigate the influence of gas injection timing (GIT) on the combustion instability of a
premixed natural gas engine, experiments were conducted under low load conditions using …

Results from computational simulations of fuel economy and engine-out emissions are
presented for light-duty conventional and hybrid vehicles powered by conventional and high …

Experiments are carried out with different GITs under 10% and 25% load conditions to
reveal the influence of gas injection timing (GIT) on combustion instability for a spark ignition …

Cycle-to-cycle variability (CCV) is detrimental to IC engine operation and can lead to partial
burn, misfire, and knock. Predicting CCV numerically is extremely challenging due to two …

Cyclic variations are inherent in the combustion of internal combustion engines. However,
extreme cyclic combustion variations limit the operation of sparkignition (SI) engines …

In this paper, the nonlinear dynamic characteristics of combustion instability in the natural
gas engine were investigated. The experiments covered the whole excess air ratio (λ) in …

This is the second part of a two-part investigation of on-board catalytic fuel reforming to
increase the brake efficiency of a multicylinder, stoichiometric spark-ignited (SI) engine. In …

Butanol is attracting more attention as an alternative fuel. The performance and emissions of
butanol/ethanol–gasoline (E10) was investigated in a spark ignition engine. Exhaust gas …
