Abstract
The utility model relates to an intake manifold of engine, which comprises a pipe body (6), an air flue (3) and a cylinder mounting flange surface (5), wherein a throttle port (2) and a pressure stabilizing cavity (4) are arranged on the pipe body (6), and a sensor boss (1) is arranged on the top of the pipe body (6) above the throttle port (2) and the pressure stabilizing cavity (4). An air temperature pressure senor of the engine can be arranged on the sensor boss to collect two groups of data of air inlet temperature and pressure, and the data collected at the position has the highest precision and stability in any parts in the engine air intake system. An electronic control unit ECU receives information provided by the sensor for processing, and emits right orders to an executer according to the processing results to control the engine. The intake manifold can satisfy the increasingly stringent requirements of discharging law rules, and simultaneously improves the dynamic property of automobiles, the fuel economical efficiency and the comfort, and greatly improves the integral property of an automobile engine.
Description
Technical field
The utility model relates to a kind of gas handling system of motor car engine, specifically relates to a kind of intake manifold of motor car engine.
Background technique
At present, motor car engine is not provided with sensor boss (as shown in Figure 1) with the pressure stabilizing cavity top of intake manifold.Air pressure probe that former motor is used and temperature transducer are installed in the engine throttle position, and therefore this two sensors installation base is not set on intake manifold.Because the pressure and temperature at engine throttle position is extremely unstable, and the temperature, the pressure that formally enter the temperature and pressure of engine air flow and this air throttle place are inconsistent, cause by the data feedback of air pressure probe and temperature sensor measurement inaccurate, thereby influence vehicle electronic control unit (ECU) according to measured load to instruction accuracy, stability that final controlling element sent, it directly causes the power character, fuel economy of automobile and travelling comfort descends and make discharging not up to standard.
The model utility content
The purpose of this utility model is to overcome above-mentioned deficiency, and provide a kind of can be to the air-flow that enters motor stream pressure and accurate, the stable engine intake manifold of temperature data by air pressure probe and temperature sensor measurement.
The purpose of this utility model realizes by following technical solution: a kind of engine intake manifold, comprise body, air flue, cylinder cap mounting flange face, body is provided with solar term mouth, pressure stabilizing cavity, on the top of described body, solar term mouth and pressure stabilizing cavity above locate to be equipped with the sensor boss.
After adopting the utility model structure, the air temperature pressure transducer of motor (being original intake air temperature sensor and pressure transducer is replaced by present advanced person's intake temperature pressure transducer) can be contained on this sensor boss, using a sensor to gather intake temperature and two groups of data of pressure, is that accuracy in the data that gather at any position in engine aspirating system, stability are the highest through the data that overtesting is gathered by this place.So, the information that electronic control unit (ECU) is accepted sensor and provided is also handled, and sends right instructions according to processing result to final controlling element, and motor is implemented control.Both satisfied more and more stricter emission regulation demands, improved power character, fuel economy and the travelling comfort of automobile simultaneously, and made the overall performance of motor car engine obtain increasing substantially.
Description of drawings
Below in conjunction with accompanying drawing and mode of execution the utility model is described in further detail.
Fig. 1 is the structural representation of known engine intake manifold.
Fig. 2 is the structural representation of the utility model engine intake manifold.
Fig. 3 is the right elevation of Fig. 2.
Embodiment
With reference to Fig. 1 as can be known, known motor car engine is not provided with the sensor boss with the pressure stabilizing cavity top of intake manifold.
With reference to Fig. 2, Fig. 3 as can be known, the utility model engine intake manifold, comprise body 6, air flue 3, cylinder cap mounting flange face 5, body 6 is provided with solar term mouth 2, pressure stabilizing cavity 4, on the top of described body 6, solar term mouth 2 and pressure stabilizing cavity 4 above locate to be equipped with sensor boss 1.Sensor boss 1 is provided with probe hole 7, bolt hole 8.The former air temperature pressure transducer that is assemblied in the engine throttle position is installed to by bolt (and bolt hole 8 of sensor boss 1) on the sensor boss 1 at all metastable intake manifold pressure stabilizing cavity of charge air flow temperature, pressure top (as shown in Figure 3), and the probe of this sensor is put in the probe hole 7 of sensor boss 1.Shown in accompanying drawing, air draught enters air flue 3 by pressure stabilizing cavity 4 and the inner participation burning of inflow engine from solar term mouth 2.
Claims (1)
1, a kind of engine intake manifold, comprise body (6), air flue (3), cylinder cap mounting flange face (5), body (6) is provided with solar term mouth (2), pressure stabilizing cavity (4), it is characterized in that: on the top of described body (6), the place, top of solar term mouth (2) and pressure stabilizing cavity (4) is equipped with sensor boss (1).
