DIESEL ENGINE POWER DOUBLE dual-mode YaMZ-238 for buses LIAZ 5256.30 MODELS

摘要

Making reconstruction diesel V-shaped 8-cylinder four-cycle engine for the bus YAM3-238 LiAZ model 5256.30 obtain dual-mode dual-capacity motor YAM3-238 by changing the arrangement of the pushers on the camshaft changing the order of engine 1-5-4-2-6- on the order of 3-7-8 1-2-4-3 of cylinders, wherein each second cylinder being closed valves, fuel injection nozzles is made, a crankshaft design enables it to do neck disposed so that every four piston when turning knees atogo shaft by 180 ° are at TDC, distributing cylinders so where the first cylinder accept two cylinders: the first and fourth, for a second cylinder - the second and the third, the fourth cylinder - the fifth and the eighth and third cylinder - sixth and seventh such distribution corresponds to the order of operation the 4-cylinder 4-stroke engine with the order 1-2-4-3 operation, while reducing the load on the vehicle varies the fuel supply to the cylinders, by turning off the fuel supply to each injector a second, in the first to fourth clock cycle, in the second to the second, in hours tvertom the eighth, in the third to sixth, which saves fuel.
