A petrol engine (known as a gasoline engine in American English) is an internal combustion engine with spark-ignition, designed to run on petrol (gasoline) and similar volatile fuels. In most petrol engines, the fuel and air are usually mixed after compression (although some modern petrol engines now use cylinder-direct petrol injection). The pre-mixing was formerly done in a carburetor, but now it is done by electronically controlled fuel injection, except in small engines where the cost/complication of electronics does not justify the added engine efficiency. The process differs from a diesel engine in the method of mixing the fuel and air, and in using spark plugs to initiate the combustion process. In a diesel engine, only air is compressed (and therefore heated), and the fuel is injected into very hot air at the end of the compression stroke, and self-ignites.
Raw material crushing device used before fermentation of organic fertilizer
The utility model discloses a raw material crushing device before fermentation of an organic fertilizer. The raw material crushing device comprises a carrying travelling trolley, a crushing mechanism and a feeding lifting mechanism, the feeding lifting mechanism lifts organic fertilizer raw materials and conveys the organic fertilizer raw materials to the smashing mechanism. The crushing mechanism comprises a gasoline engine mounting frame and a horizontal crusher mounting frame which are fixed on the carrying traveling trolley, a gasoline engine arranged on the gasoline engine mounting frame, and a horizontal crusher which is arranged on the horizontal crusher mounting frame and is connected with the gasoline engine; the lower receiving hopper is arranged on the horizontal crusher and is connected with the feeding lifting mechanism; the lower receiving hopper receives organic fertilizer raw materials conveyed by the feeding lifting mechanism; the feeding lifting mechanism comprises a bucket elevator fixed to the carrying traveling trolley, a feeding hopper assembly arranged on the lower portion of the bucket elevator and fixed to the carrying traveling trolley, and an upper receiving hopper assembly arranged on the upper portion of the bucket elevator and communicated with the lower receiving hopper.

IMPROVED METHOD FOR ESTIMATING AIR FILLING IN A SUPERCHARGED PETROL ENGINE
The method is of the type in which the air filling (R_CYL) of the internal combustion engine (MT) is estimated by means of an acoustic coefficient (CA) applied to a gas pressure (PR) in an air intake distributor of the engine. According to the invention, the method includes controlling the evolution of the acoustic coefficient in a transitional zone between an atmospheric zone and a supercharged zone according to a law that takes into account an opening position (PP) of a throttle body (PD) of the internal combustion engine.
