Two-stroke gasoline engine lubricants

World of petroleum products, 2022
The article considers the design and lubrication of small 2-stroke engines installed on snowmobiles, quad bikes, motorcycles and drones. The compositions of the 2-stroke engine oils, base oils and additives, actual specification JASO, NMMA, API, TISI and ISO are analysed. Concern the short characteristics of JASO engine test methods.

Novel Two-Stroke Engine Concept, Feasibility Study

SAE Technical Paper Series, 2003
<div class="htmlview paragraph">A novel two-stroke engine concept is introduced. The cylinder scavenging takes place during the upward motion of the piston. The gas exchange valves are similar to typical four-stroke valves, but the intake valves are smaller and lighter. The scavenging air pressure is remarkably higher than in present-day engines.

Conventional two‐stroke engine lubrication

Industrial Lubrication and Tribology, 1997
Gives the results of trials conducted in China which show the use of top‐grade, low smoke, part synthetic two‐stroke oil gives better performance and four times longer engine life than the four‐stroke engine oils generally used to lubricate two‐stroke engines in China. Sets out existing and proposed international standards for two‐stroke engine oils.

Scavenging the two-stroke engine

Progress in Energy and Combustion Science, 1990
Abstract The scavenging process is the most important factor controlling the efficiency and performance characteristics of a two-stroke-cycle engine. This article reviews and assesses experimental and theoretical methods, which have been applied during the past three decades, to evaluate the success of the scavenging process.

Two-stroke hydrogen injection engine

International Journal of Hydrogen Energy, 1979
Some of the advantages of the two-stroke hydrogen injection engine developed by Musashi Institute of Technology are given. Flashbacks never occur. Higher output than with a gasoline engine is obtainable because the amount of mixture is larger, since only air is introduced.

The Two-Stroke Rotary Engine

SAE Technical Paper Series, 1998
<div class="htmlview paragraph">An innovative rotary engine uses a rotor that executes pendulum-like oscillatory rotation. This is converted into uniform rotation of the drive shaft by a simple mechanism. The engine also employs parameter resonance. The new design is compact and lightweight.

Two-Stroke Engines

1992
The absence of the separate induction and exhaust strokes in the two-stroke engine is the fundamental difference from four-stroke engines. In two-stroke engines, the gas exchange or scavenging process can have the induction and exhaust processes occurring simultaneously.
