Abstract
The utility model relates to a teaching aid, in particular to a multiple fuel injection time-sequence experimental platform for an automobile engine. The multiple fuel injection time-sequence experimental platform comprises a fuel tank (1), a fuel pump (2), a high-pressure fuel pipe (3), fuel-injection pipes (5) and observation fuel cups (8) and is characterized in that the experimental platform is provided with a single-chip microcomputer program controller IC (integrated circuit) which is externally connected with a vehicle-speed control switch K3 (14), an air throttle control switch K4 (13) and a fuel-injection time-sequence changeover switch K5 (12); and solenoid valves (6) are installed on the fuel-injection pipes (5) and are respectively connected with the single-chip microcomputer program controller IC. The multiple fuel fuel-injection time-sequence experimental platform has the beneficial effects that the single-chip microcomputer program controller is adopted, therefore the fuel-injection states of various automobile engines can be simulated through one experimental platform, and the versatility of equipment is improved; the experimental platform has the characteristics of simple structure, low manufacturing cost, stable working and the like and provides favorable conditions for reduction of the instruction cost and improvement of teaching quality.
Description
Technical field
The utility model relates to a kind of teaching aid, the multiple fuel injection sequential of promptly a kind of motor car engine experiment table.
Background technology
The automobile major student need understand the working condition of motor car engine, particularly the oil spout situation of engine oil cylinder.For this reason, each relevant school mostly has been equipped with motor car engine oil spout simulated experiment platform., existing experiment table all is special-purpose experiment table, and an experiment table can only be simulated a kind of oil spout state of vehicle.Because the automobile kind is a lot, need to be equipped with the kinds of experiments platform, cause the raising of instruction cost.For the relatively poor school of condition, because be difficult to be equipped with experimental facilities, teaching efficiency will be affected.
Summary of the invention
The purpose of this utility model provides a kind of fuel injection condition that can simulate various different motor car engines, and the multiple fuel injection sequential of motor car engine simple in structure, with low cost experiment table.
Above-mentioned purpose is realized by following technical scheme: develop the multiple fuel injection sequential of a kind of motor car engine experiment table, comprise fuel tank, oil pump, high-pressure oil pipe, spray bar, atomizer, observation lubricating cup, be characterized in: said experiment table is provided with the Single Chip Microcomputer (SCM) program controller, the single-chip microcomputer program controller picks out cruise control switch, air throttle gauge tap, oil spout sequential change-over switch, solenoid valve all is housed on the spray bar, and each solenoid valve interrelates with singlechip controller respectively.
Said fuel tank is provided with pump switch and FP Fuel Pump Relay, and pump switch K2 and singlechip controller IC interrelate.
The beneficial effects of the utility model are: adopt the single-chip microcomputer program control device, the injection process that can simulate various motor car engines by an experiment table, improved the versatility of equipment, and have characteristics such as simple in structure, cheap, working stability, for reducing instruction cost, improving the quality of teaching provides advantage.
