Diesel with a hand to start, usually small power diesel engines, such as tractors and the like. It works as follows: 1, start with one hand pressed diesel engine cylinder head (or other places for linkage) of the "step-down bar" so that when shaking the cylinder space is not at "full sealed state" and easy to shake, Another shake of the hand, so that the gear inside the machine drive link, reciprocating piston for runtime; 2, when shaken, Linyi tractor, diesel fuel injection system under the action of gears, cams, while the cylinder inside an "as required" pumping diesel mist; 3, when the hand reaches a certain speed, link, movement of the piston has reached a certain speed; 6, Junan tractor, although artificial buck lever release "Shake does not move," crank, but due to the shaking when the flywheel of the diesel engine has been "Save" the momentum, then still driven by the crankshaft, connecting rods, piston continues to move, when the piston passes the top dead center, injected diesel oil at a high temperature compressed gas produced "spontaneous combustion" phenomenon, thus driving piston, link, crankshaft to the cylinder "bottom dead center" direction, tractor, external work, output power, for power After the completion of the piston through the lower dead point, the role of flywheel inertia force, tractor prices, up dead direction, while the exhaust valves are open at the top cam action, to the outside vent; Junan hand _ White Dragon tractor machinery (Online) _ tractor by Shandong Bailong Machinery Co.
