Перевести а то у меня бред какой то получается(( the petrol engine must usually be set in motion before an explosion can take place and power can be developed; moreover, it cannot develop much power at low speeds. these difficulties have been overcome by the use of gears and clutches, which permit the engine to work at a speed higher than that of the wheels, and to work when the vehicle is at rest. an electric starter receiving its current from the storage battery, turns the crankshaft, thus starting the petrol engine. the starter motor is of a special type that operates under a heavy overload, producing high power for very short periods. in modern cars, the starter motor is automatically actuated when the ignition switch is turned on.
