A fuel mixture for two-stroke engines and four-stroke engines, in particular for model engines, consists of a microfiltered mixture of methanol with an addition of 8 to 25 % by volume of polyglycol, relative to the total quantity of the fuel mixture. The fuel mixture may contain an added...
The Compression Stroke Now the momentum in the crankshaft starts driving the piston back toward the spark plug for the compression stroke. As the air/fuel mixture in the piston is compressed, a vacuum is created in the crankcase. This vacuum opens the reed valve and sucks air/fuel/oil in...
A lubricant-fuel mixture for two-stroke internal-combustion engines contains one or more reaction products of sulphur or a phosphorus sulphide with an unsaturated hydrocarbon or with a fatty oil, the total weight of sulphur based on the lubricant component of the mixture being 0.1 to 2%, and th...
Air/fuel mixture supply device for a two-stroke internal- combustion engine, of the type with scavenging by compressed air in the casing, comprising at least one cylinder, a piston capable of reciprocating motion in the cylinder, and a scavenging-air compression casing, the cylinder comprising at...

as quite a few casual riders and even professional racers still prefer the old-school feel and sound of these engines. This is especially evident in enduro racing, where KTM’s own Manuel Lettenbichler won theon a fuel-injected two-stroke. At the end of the day, the Austrian manufacturer ...
In Two-Stroke engines, the cylinder filling efficiency is antithetical to the cylinder scavenging efficiency; moreover, both of them are influenced by geom... AP Carlucci,A Ficarella,G Trullo - 《Energy Conversion & Management》 被引量: 6发表: 2016年 Analysis of Mixture Formation Process in...
(42), in the course of which fuel being supplied from the tank (1) at the fuel aspiration connector during the pump aspiration stroke is aspirated via a flap valve (61) into the compression chamber (51) located upstream of the pump piston, and is pumped during the compression stroke via...
