<p>The combustion engine (1) with fuel injection comprises a throttle valve (6) in the air intake (7) and, in parallel with the throttle, an idling air by-pass (9) with flow adjusting screw (16). The by-pass is contained in a housing (14) which is separate from the throttle valve housing (5), and is directly secured to an engine component which rapidly reaches operating temp. e.G. the cylinder head (1'), so that it is heated by heat transfer therefrom. The inlet manifold (2, 3) may contain a starting fuel injector (18) with air supply (13) from a warm air valve (10) the by-pass joining with this air supply line (13).</p> |
