Abstract
The invention discloses a throttle body, which comprises a throttle body shell (7), a throttle (5) and an electric heating circuit, wherein the electric heating circuit comprises a water temperature sensor (1), an ECU (2), a relay (3), a power supply (4) and a heating resistor (6); the heating resistor (6) is arranged inside the throttle (5); and when the environmental temperature measured by the water temperature sensor (1) is over-low, the ECU (2) controls the suction and shut of the relay (3) and controls the switch-on of the heating circuit. The throttle body greatly simplifies the structure of the conventional cold starting system, furthest reduces the cost while ensuring the cold starting performance, is convenient to arrange, and saves the arrangement space.
Description
Technical field
The present invention relates to technical field of engines, particularly a kind of throttle body.
Background technique
The cold starting system of alcohols automobile generally is the purpose that the gasoline that utilizes in the drop tank is realized cold start-up at present.And adopt this kind mode, generally need punch on engine intake manifold increases oil sprayer.So way has not only increased expense, and has caused suitable difficulty to engine arrangement.
Summary of the invention
The present invention passes through engine air throttle is increased electric heating function, thereby solves the cold start-up problem of alcohols and other cold start-ups difficulty motor.
The present invention specifically discloses a kind of throttle body, comprises throttle body shell and closure, it is characterized in that: also comprise being used for cold start-up by electric heating circuit.
Further, described electric heating circuit comprises power supply and heating resistor, and wherein heating resistor is arranged at closure inside, and the positive and negative level of power supply is connected to the heating resistor two ends.
Further, described electric heating circuit also comprises relay, is controlled the conducting of electric heating circuit by the adhesive of relay.Described relay is controlled by ECU, crosses when low control relay adhesive, the conducting of control electric heating circuit when ECU records ambient temperature by cooling-water temperature sensor.
Further, the positive pole of described power supply is connected to relay, and the output terminal of relay is connected to an end of resistance.Described power supply is a storage battery, and the electric current of storage battery raises the temperature of heating resistor rapidly, when cool air is heated during by closure, realizes cold start-up.
The present invention has simplified the structure of former cold starting system greatly, when guaranteeing cold starting performance, greatly the reduction of degree cost, arrangement convenience, and save arrangement space.

Embodiment
Below in conjunction with embodiment shown in the drawings the present invention is specifically described.
As shown in Figure 1, heater circuit comprises cooling-water temperature sensor 1, ECU2, relay 3, storage battery 4 and heating resistor 6, wherein heating resistor 6 places the inside of closure 5, when recording ambient temperature by cooling-water temperature sensor 1, crosses low the time ECU 2,3 adhesives of ECU 2 control relays, make that the heater circuit of heating closure 5 is open-minded, the electric current of battery 4 raises heating resistor 6 temperature rapidly, as shown in Figure 2, when cool air is heated during by throttle body assembly 8 (electronic air throttle body), thereby realize the purpose of cold start-up.
For the mechanical type throttle body, because of bypass valve and throttle position very close, the purpose of pre-heating intaking in the time of also reaching cold start-up.
