Crevice volume effect on spark ignition engine efficiency
… to quantify the effect of the piston crevice on engine efficiency. The simulation study breaks down the loss mechanisms on brake efficiency at different displacement volumes (300 - 500 cc) and compression ratios (8-20). Experiments focus on indicated efficiencies for a narrow range of compression …

A computational and experimental study of spark ignition engine combustion
This work focuses on aspects of combustion in a spark ignition engine. A pent-roof research engine was used to generate an experimental data set which was combined with a preexisting data set from a disc-chamber research engine. The combined dataset was used to refine a thermodynamic spark ignition …

Addressing nonlinear combustion instabilities in highly dilute spark ignition engine operation
… operation is a promising approach for increasing spark-ignition engine efficiency, in the form of either lean burn (air dilution) or EGR (inert dilution). High levels of charge dilution, however, lead to cyclic variability that is largely deterministic in nature. The determinism and nonlinear …

Fuel component effects on hydrocarbon emissions from a spark-ignition engine
… in order to determine the sensitivity of the engine-out emission levels of two olefins, 2-methylpropene (2MP) and 1,3-butadiene, to selected fuel components. In this experiment, a base fuel was perturbed with the following four major fuel components: MTBE, toluene, m,p-xylene, and iso-octane. …

Combustion characteristics of a spark ignition engine operating with liquid lpg injection
… of alternative fuels in internal combustion engines. Liquefied petroleum gas (LPG) is one of the most popular alternative fuels for spark ignition (SI) engines that received lots of attention due to its availability and acknowledged superior properties than gasoline. However, detail analysis …

Development of a High Speed Data Acquisition System for Spark Ignition Engine
Full engine control can only be accomplished with multi-input multi-output (MIMO) control system requiring measurement of variables for which no sensor/instrument is yet available in the Renewable Energy and Engines Laboratory, therefore a less detailed single input single output (SISO) engine …

Fuel Preparation in the Cylinder of a Port-Injected, Spark Ignition Engine
… stroke with in-cylinder swirl. Increasing engine speed from 200 to 1200 rpm was much less effective for enhancing mixing than was increased swirl. Finally, the injector spray quality was found to affect the droplet sizes passing into the cylinder only for an open-valve injection timing.
