Abstract
On an intake pipe (1) developed for an internal combustion engine of a motor vehicle which leads to an air filter housing (3), there is arranged on the outside on the intake pipe (1) a housing (11) containing an engine-control electronics. The housing (11) has a bottom (13) which is cooled by the stream of air in the intake pipe (1). In this way, despite the great closeness of the internal combustion engine, sufficient cooling is obtained of the electronic structural parts of the engine-control electronics.
Claims9
An intake pipe assembly for an internal combustion engine of a motor vehicle, the pipe extending to an air filter housing of the engine, the assembly comprising:
- a housing on the outside of the pipe;
- an engine control electronics disposed in the housing;
- an air-mass sensor disposed in the bottom of the housing of the engine-control electronics;
- wherein the housing has a bottom forming a part of the pipe and being cooled by air flow in the pipe;
- and
- the electronics comprises a circuit board, and the air-mass sensor has a sensor electronic system which is arranged on the circuit board, and the air mass sensor is directly connected to the circuit board to form therewith a unitary assembly.
