As the interest on the air pollution is gradually rising up at home and abroad, automotive and fuel researchers have been working on the exhaust emission reduction from vehicles through a lot of approaches, which consist of new engine design, innovative after-treatment systems, using clean fuels and fuel quality improvement. However, a study that the fuel quality affect on exhaust emission from vehicle. FT-IR spectroscopy, useful technology for simultaneous and continuous measurement of the various components of the automotive exhaust gas, is utilized to a few unregulated exhaust emissions measurement of the irregular gasoline fuel including the regulated exhaust emissions. This research shows that the irregular gasoline fuel had some problem that cause of ambient pollution, power decreasing, fallen to safety and trouble of engine. Also, based on these problem, this paper discusses the influence of gasoline quality on automotive exhaust emissions.

This Study was conducted to evaluate relation with engine oil property changes and engine performance for the diesel engine. This test was performed on about 12 ℓ, 6 cylinder. Heavy Duty Engine. And Low SAPS 10W30 Engine Oil was used. Test procedure and method was in accordance with modified CEC L-57-T97(OM441LA) Method. In this study, Engine power, Blowby Gas, A_F, TAN, KV and Metal Components were presented to evaluate relation with engine oil property changes and engine performance. TAN, KV and Metal Components were generally increased but Engine performance did not change. This results mean that property changes did not make effect on engine performance because those were not as enough as to affect engine performance.

Engine oil is an oil used for lubrication of various internal combustion engines. The main function is to reduce wear on moving parts; it also cleans, inhibits corrosion, improves sealing, and cools the engine by carrying heat away from moving parts. In engines, there are parts which move against each other. Otherwise, the friction wastes the useful power by converting the kinetic energy to heat. Those parts were worn away, which could lead to lower efficiency and degradation of the engine. It increases fuel consumption, decreases power output, and can induce the engine failure. This study was conducted to evaluate the relation between engine oil property changes and engine performance for the diesel engine. This test was performed by using 12L, 6 cylinder, heavy duty engines. Low SAPS 10W30 engine oil (two type engine oils) was used. Test procedure and method was in accordance with the modified CEC L-57-T97 (OM441LA) method. In this study, TAN, TBN, KV and metal components, engine power, blowby gas, A_F were presented to evaluate the relation with engine oil property changes and engine performance. TAN, TBN, KV and metal We found that the components were generally increased but engine performance did not change. This results mean that property changes did not affect on engine performance because those were not enough to affect engine performance.
