The investigation was performed on a turbocharged, water-cooled, direct-injection diesel engine, equipped with a common-rail injection system. The engine equipment included an exhaust gas recirculation system controlled by an external driver, a piezo-quartz pressure transducer to detect the in-cylinder...
To study the effects of charge compositions on the ignition and combustion process of diesel engine, the flame photos of diesel combustion process with full throttle under different charge compositions were recorded using high-speed camera on the optical engine with observation window on the cylinder-...
Measurements of performance and emissions of a Detroit Diesel 1-71 engine fueled with natural gas have been made using high-pressure direct-injection (HPDI). Natural gas is injected late in the compression cycle preceded by pilot injection of conventional liquid diesel fuel. With 6 nozzle holes ...
Engine performance and exhaust gas emissions of methanol and ethanol–diesel blends In this study, the effects of methanol–diesel (M5, M10) and ethanol–diesel (E5, E10) fuel blends on the performance and exhaust emissions were experiment... C Sayin - 《Fuel》 被引量: 297发表: 2010年 ...
- 《International Journal of Engine Research》 被引量: 33发表: 2007年 PERFORMANCE AND HEAT RELEASE ANALYSIS OF A PILOT-IGNITED NATURAL GAS ENGINE The influence of engine operating variables on the performance, emissions and heat release in a compression ignition engine operating in normal diesel ...
Overall, the compressed natural gas (CNG)-diesel dual fuel engine performs better at high power, but is still lower than all-diesel operation [32]. However, there are some defects at low load, especially in HC and CO emissions [33]. Show abstract Engine knock detection for a multifuel ...
Effects of variations in natural gas composition on the autoignition of natural gas under direct-injection (DI) diesel engine conditions were studied experimentally in a constant-volume combustion vessel and computationally using a chemical kinetic model. Four fuel blends were investigated: pure methane,...
The DI (Direct Injection) Diesel engine, which is inherently capable of achieving very low CO2 emissions, is affected by PM (Particulate Matter) that is the typical emission of turbulent diffusion flames and has the drawback of high NOx (nitrogen oxides) emissions. In Europe, the recent progre...
The exhaust gases from a petrol engine are treated to remove unburnt hydrocarbons. Treatment occurs in a catalytic converter (12) positioned at the inlet to the exhaust pipe (8a). The catalyst is surrounded by a gas collection chamber (3) which contains an adsorber (15) of hydrocarbons. Exh...
Fig. 5. A typical diesel engine [66]. The diesel engine was invented by Rudolf Diesel in the year 1892 by improving Nikolaus Otto׳s gas engine efficiency. Although the diesel engine has certain similarity with petrol internal combustion engines, diesel engine is using heat of compression to...
