During the intake process, working volume of cylinder is filled with a fresh charge. As noted, charge consists air in diesel engine, and engines ignition from an electric spark (gasoline carburetor or gasoline fuel injection, as well gas) – mixture vapors light combustible gas.

Nowadays, automobiles and motorcycles manufacturer produced more powerful efficient engines. This engine usually has high compression pressure to achieve performance economic gasoline consumption. Unfortunately, only few people known that requires octane number gasoline. The aim of this research were find out the differences power & torsion output one cylinder combustion which given several...

This review paper summarizes major developments in vehicular emissions regulations and technologies from 2014. The paper starts with the key regulatory advancements in the field, including newly proposed Non-Road Mobile Machinery regulations for 2019-20 in Europe, and the continuing developments towards real driving emissions (RDE) standards. An expert panel in India proposed a roadmap through ...

The major aim of the research is to investigate ability biogas as an alternative fuel for gasoline-powered Spark Ignition (SI) engine. In this study, biogas/gasoline mixtures containing different ratios biogas, gasoline, and were tested in SI engine with increased compression ratio at loads constant speed. According comparison utilization generally decreased Brake Thermal Efficiency (BTE), whil...

Homogeneous charge compression ignition (HCCI) seems to be the most promising solution for gasoline engines in the light of future emissions regulations. This novel combustion technique allows for significant reduction of fuel consumption and engine-out NOX emissions at low and medium engine load/speed conditions. High heat release rate enables realization of the Otto cycle close to ideal, incr...

PROBLEM: There are strong associations between exposures to motor vehicle-derived particles and cardiopulmonary morbidity and mortality but there have been few studies that realistically examined possible differences in the effects of gasoline versus diesel-powered engine emissions. The Caldecott Tunnel, which has segregated traffic patterns, offers an opportunity to test the hypothesis that th...

New HCCI/CAI Combustion Process Development: Methodology for Determination of Relevant Fuel Parameters — To pass the simultaneous emission requirements for near zero pollutant and low CO2 levels, which are the challenges for future powertrains, many research studies are currently carried out over the world on new engine combustion processes, such as controlled auto-ignition (CAITM) for gasoline...

Health concerns over ultrafine (<100 nm) particles in the urban atmosphere have focused attention on measurement and control of particle number as well as mass. Gasoline-engined as well as diesel-engined vehicles are likely to be within the scope of future particulate matter (PM) emission regulations. As a potential option for after-treatment of PM emissions from gasoline engines, the trapping ...

The International Agency for Research on Cancer has classified diesel exhaust as a carcinogen based on lung cancer evidence; however, few studies have investigated the effect of engine emissions on bladder cancer. The purpose of this study was to investigate the association between occupational exposure to diesel and gasoline emissions and bladder cancer in men using data from the Canadian Nati...
