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...

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 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...

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)...
