In order to study factors affecting lean combustion limit, an experimental study was carried out on a spark- ignited engine fueled with compressed natural gas and hydrogen blends. Effects of ignition timing, hydrogen fraction, engine speed, throttle opening, coolant and oil temperature were...

The experiments were performed using a modified six-cylinder turbocharged direct injection diesel engine with diesel of different distillation ranges to investigate the effects of (exhaust gas recirculation) EGR on engine performance and emission characteristics of low-temperature combustion...

In order to investigate the effects of altitude on the brake thermal efficiency of heavy-duty diesel engines, an experimental study on a heavy-duty diesel engine operating at various altitudes was conducted. Tests were conducted in low and moderate load and speed conditions. Brake thermal...

The combustion and emissions of n-butanol/biodiesel dual-fuel injection were investigated on a diesel engine based on experiments and simulations. n-Butanol was injected into the intake port, while soybean biodiesel was directly injected into the cylinder. Three different premixed ratios (rp)...

CO2 is a significant greenhouse gas. CO2 emissions result mainly from energy consumption, which is closely related to the rate of economic development, efficiency of energy use and the structure of the energy-supply system. We estimate CO2 emissions in Shanghai for 1990 and 2010 and compare our...
