Internal combustion engine of the injection type, and plate intended for fitting between the inlet ports of a cylinder block of such an engine and an inlet tube.

摘要

An internal-combustion engine of the injection type comprises a cylinder (1) which is provided with an inlet channel (4) with inlet valve (5). An inlet tube (2) with fuel injector (3) is fixed on this inlet channel. A heating element with a heat sink (11, 12), electrical resistance means (16) and current supply means (14, 17, 18, 20) projects into the inlet channel of the cylinder. In order to avoid cold spot problems, the heating element (11 to 16) is not fitted in a thermally insulated manner, and is integrated in a plate (6) which is clamped between the inlet tube (2) and the head of the cylinder (1). The electrical resistance means (16) are provided in a chamber (11) whose top face forms part of the heat sink. A cylindrically curved wall (12) preferably connects to the chamber (11) and is connected to this plate by means of material bridges (10).
