In this study, the effect of nitromethane addition to gasoline fuel on engine perfor-mance and emissions in a single-cylinder spark-ignition was experimentally inves-tigated. By adding 5% 10% gasoline, experiments were carried out at full load six different cycles. Engine load, consumption, exhaust gas tempera-ture, measured during experiments. According experimental data, power, torque, specif...

The present study aims at investigating the amount of exhaust gases emissions of a 4-cylinder gasoline-ignition engine. An experimental study of an ignition engine management system has been conducted for emissions optimization, using Winols specialized software. In order to achieve a steady state conditions in the experiments, the temperature of the water and engine oil before each test reache...

This paper analyzes the vibration behavior of an in-line 4-cylinder, 4-strokes, internal combustion turbocharged direct injection gasoline engine. A detailed multi-body numerical model of the engine prototype was used to characterize the whole engine dynamic behavior, in terms of forces and velocities. The crank train multi-body model was created starting from engine geometrical data, and the a...

To improve the responsiveness of engine speed control to disturbances, robust controls were investigated by simulation. The intake air control system of a gasoline engine is a typical nonlinear system, and the disturbances and parameter perturbations are generally regarded as being the unstable factors with regard to engine control. In this paper, a Mean-Value Engine Model (MVEM) with disturban...

Today, the prices of fossil fuels such as gasoline and diesel are skyrocketing, oil depletion air pollution major challenges for us auto industry in particular. Natural gas has known a potential alternative fuel internal combustion engines because its advantages octane number, which is higher than that gasoline, low heat value comparison with safety use. This paper presents study on influence s...
