5.2. Engines with fuel injection
Into structure of fuel system enter: – A fuel tank; SYSTEM OF ELECTRONIC INJECTION OF FUEL In system of direct injection fuel is entered into each cylinder through atomizers. Injection system the processor block (block ECM) which sets duration of impulses (quantity of fuel) in reply to operates signalling from various gauges of the engine. The quantity of air in a gas mixture is set throttle заслонкой. Pressure of fuel is regulated by means of the vacuum distributive valve (VSV-valve). On the heated-up engine the valve reduces pressure of fuel at start and impoverishes a mix. On late models management of the VSV-valve обеспечиваетсяпроцессорным the block, on early models – the special monitoring system of start-up of the heated-up engine (system High Temperature Line-Up Pressure). THE FUEL PUMP AND HIGHWAYS Fuel circulation is provided with the electropump through pair steel tubes. Return of the evaporated fuel to a tank is provided with catching system through a separate tube. The pump works at receipt of basic impulses from the ignition block on the processor block. In the absence of these impulses the pump is disconnected after 2–3 seconds EXHAUST SYSTEM The system structure in addition includes the gauge of oxygen and 3-componental neutralizer which concerns system of clearing of the fulfilled gases and is built in in an exhaust pipe for the purpose of decrease in toxicity of emissions. |
