TL;DR: In this article, the effect of diesel injection timing on combustion and emissions characteristics of a 6-cylinder turbocharged intercooler diesel/natural gas dual fuel heavy-duty engine was investigated.

TL;DR: In this paper, the authors investigated the effects of ignition timing on combustion and emissions of an SI methanol engine with added hydrogen at different engine speeds, and found that more hydrogen increases the indicated mean effective pressure, maximum cylinder pressure and maximum heat release rate, and decreases the ignition delay, combustion duration.

TL;DR: In this paper, the effects of intake temperature on mixture formation, combustion processes, and unregulated emissions of formaldehyde and unburned methanol were numerically simulated for a stratified-charge DISI engine during cold start.

TL;DR: In this article, an organic Rankine cycle coupling free piston compressor (ORC-FPC) system has been proposed, which is used in recovering the waste heat of exhaust gas from the stationary compressed nature gas (CNG) fueled internal combustion compressor.

TL;DR: In this paper, the effects of ozone (O3) addition from 0 to 7000 ppm in the intake manifold on cylinder pressure history, ignition delay, cylinder temperature history, and formaldehyde unburned methanol emission of a direct injection spark ignition (DISI) engine during cold start and steady state conditions were simulated using computational fluid dynamics.
