This paper provides an overview of the effect of a flight altitude on knock occurrence in reciprocating SI turbocharged engines. It presents results of the computational study aimed at investigating reasons leading to knock occurrence and methods of alleviating the knock tendency of aircraft engines. Knock has been one of the key limiting factors in the development of IC engines since the first use of the technology more than a century ago. Aviation platforms are becoming increasingly widespread around the world, and turbochargers are frequently added to improve the performance of the platforms at high altitudes. Although a turbocharger provides the benefits of improved BSFC and a downsized engine, turbocharging can result in engine knock because of increasing the intake air temperature, due to a rise in the compression ratios as the air density drops.

Abnormal combustion experiments were conducted in which engine oil additives were mixed into the test fuel in order to investigate their influence on the occurrence of abnormal combustion. A four-stroke side-valve engine that allowed in-cylinder visualization of the combustion flame and light absorption measurements were used in the experiments. Different type of calcium-based engine oil additives were mixed into the primary reference fuel (PRF 50) at the same ratios at which they are found in ordinary automotive engine oil.

In recent years, an improvement of fuel economy and exhaust emission performance of internal combustion engines has been strongly required. The one of the important problems for general purpose engines is a larger amount of CO emission compared to that of automobile engines. To reduce CO and other exhaust emissions while keeping fuel efficiency high, optimization of total engine system including various design parameters is essential. In the engine system optimization process, cycle simulation using 0-D and 1-D engine model is significantly useful. The model used in the cycle simulation to define optimum design has to be capable of predicting the effect of various parameters on the engine performances. In this study, a prediction model of performance of general purpose SI engine is developed based on a commercially available engine simulation software, GT-POWER. The developed 1-D engine model was validated using 3-D CFD simulation and experimental results.

A new air-cooled SI two-stroke gasoline engine has been developed for an arborist-chainsaw. This engine has a displacement of 25 mm3 and generates about 1.1 kW and complies with the latest CARB and EPA exhaust regulations by optimizing scavenging flows and the use of a catalytic converter. Characteristics of lightweight, compact and high power-to-weight ratio are required for handheld chainsaws, especially for arborist chainsaws. As a matter of course, these characteristics are needed for engine itself in order to satisfy such market requirements for hand-held power equipment. To realize lightweight and compact design, the placement of catalytic converter is optimized for the engine and a two-piece crankshaft is adopted.
