“…For premixed combustion engine, the engine performance mainly depends on the in-cylinder combustion process. In previous investigations [2][3], it has been summarized that the in-cylinder combustion process is mainly affected by following three factors in gasoline engine: 1) the effect of engine structure (such as compression ratio, location and number of spark plugs); 2) the effect of quality and component of air/fuel mixture; 3) the effect of operation conditions (engine speed, load). Among them, engine structure affects flame propagation by generating different flow patterns.…”

Misfire has attracted lots of researcher?s attention as a common engine fault, but most researchers focus on misfire diagnosis. For motorcycle engines, misfire is more worth to investigate because of the more extensive operation windows. The misfire degree is detected by experiment and its effect mechanism on subsequent cycles is investigated through simulation. Its effect is analyzed through two aspects: 1) misfire cycle leaves about 10.8% fuels that participate in next cycle working process, leading to richer fuel/air mixture. But 13.8 % lower of in-cylinder peak pressure than normal scenario is observed. Then interaction between flame propagation and flow field is discussed. The effect of misfire on flow field intensity is small, but it changes flow field structure largely. This change evolves persistently during subsequent processes, superimposing the lower temperature brought by misfire of last cycle, resulting in slower flame propagation and thus lower thermal efficiency for misfire scenario. This impact can last 3-4 subsequent cycles until gradually fades away; 2) for pollutants formations, the NO emission is lower for misfire scenario due to the lower in-cylinder temperature, but HC emission is higher. Although higher CO is produced during main combustion phase for misfire scenario, it converts to CO2 more largely during post flame stage, resulting in almost the same final amount relative to normal scenario.

The search for suitable alternative for fossil fuel has been a challenge to the research community for the past two decades. So many alternatives have been identified and tested. However, a complete replacement cannot be provided without any penalties of cost, excess emission, poor operation, etc. The alcohols gave a new opportunity and a solution for the above problem but had some setbacks of increased density and lower octane number. The present workfocuses on striking a balance between advantages and disadvantages by using oxygenated additive with gasoline fuel. The additive cerium oxide (CeO2) along with methyl tertiary butyl ether (MTBE)offers many advantages. The seven samples, namely M10, M15, M20, M25, M20+50mg/l, M20+100mg/l, M20+150 mg/lhave been preparedand tested on Sprk Ignition (SI) engine. Here, 10, 15, 20,and 25 denote the MTBE volume in blends and 50 mg/l, 100mg/l, and 150mg/l indicate the CeO2 in blends. The results have shown that only MTBE has caused an increase of 4% in Brake Thermal Efficiency (BTE)with M15 and then BTE has improved by 3% with M15+100mg/l compared with pure gasoline. And, fuel consumption has also been reduced upto 9% with M20 and 11% with M15+150mg/l compared with pure gasoline. The maximum HC and CO reductions have also been observed from M20 and M20+150mg/l ; it was up to 19% and 22%, 23% ,and 25% of HC and CO with M20, M20+ 150mg/l. However, there has been an increase in CO2 emission level because of excessive unburnt hydrocarbon (HC) reduction. The MTBE with CeO2 has proved to be suited to all running conditions. The blends having more amounts of additive produce good combustion characteristics yet it should be restricted within 20 vol% of MTBE and 150mg/l of CeO2.
