Single-cylinder 125 cc Stepped-piston Engine for Mobility and Portable Power Generation Applications [PDF]
International Journal of Technology, 2016 Two-stroke engines are far simpler than four-stroke engines from a physical perspective. For a given brake output, two-stroke engines are lighter, easier to work on, and provide higher power-to-weight ratio than four-stroke engines, making them ...

Measurement of Trapping Efficiencies of a Two-Stroke Engine
Transactions of the Japan Society of Mechanical Engineers, 1962 A method for the measurement of trapping efficiencies of a two-stroke gasoline engine through the exhaust gas analyses is investigated. Theoretical formulas for obtaining the trapping efficiency are introduced which can be applied to a rich or a weak mixture operation.

After-Running in a Two-Stroke Gasoline Engine
Bulletin of JSME, 1970 problems in abnormal combustion have often arisen in high compression engines of recent passanger cars. One of them is after-running which is the continuation of the engine running by autoignitions after electrical ignition cutoff. In this phenomenon the ignition of fuel-air mixture is closely related with the engine speed.

Skeena: Efficient and Consistent Cross-Engine Transactions [PDF]
Proceedings of the 2022 International Conference on Management of
Data, 2021 Database systems are becoming increasingly multi-engine. In particular, a main-memory database engine may coexist with a traditional storage-centric engine in a system to support various applications. It is desirable to allow applications to access data in both engines using cross-engine transactions.

Modeling of two-stroke aviation piston engines for control applications
Advances in Mechanical Engineering, 2023 Two-stroke Aviation Piston Engines are multivariable systems with severe non-linear dynamics, making their modeling challenging for control engineers. Although many studies have been conducted on simplified modeling of four-stroke gasoline engines and ...

THE INFLUENCE OF THE INJECTION TIMING ON THE PERFORMANCE OF TWO-STROKE OPPOSED-PISTON DIESEL ENGINE [PDF]
Applied Computer Science, 2018 The performance of the engine strongly depends on the parameters of the combustion process. In compression ignition engines, the fuel injection timing has a significant influence on this process.

Pengaruh Penambahan Langkah Kerja terhadap Unjuk Kerja Motor Bakar
Rekayasa Mesin, 2020 The duration of fuel-air diffusion in the 4 stroke combustion engine is relatively short, which is 0.02 seconds at 3000 rpm so that at high rotation the level of homogeneity of the fuel-air mixture becomes low.
