Arrangement for supplying a maximum quantity of fuel
First Claim
1. A method of limiting a quantity of fuel to be supplied to a combustion engine of a motor vehicle, comprising the steps of defining in dependency on load and rotary speed a first quantity of fuel to be supplied, determining air density of the surrounding air, determining in dependency on the air density and rotary speed a second quantity of fuel which is a limit for said first quantity, and limiting said first quantity of fuel to be supplied to the engine to said second quantity.

Abstract
A method of and arrangement for supplying a maximum quantity of fuel which is supplied to a combustion engine in certain operational conditions independent of rate of airflow and rotational speed is provided with an altitude-correcting signal which depends the maximum amount of fuel to be supplied on the air density of the actual operational altitude of the combustion engine. Through the provision of such an altitude-correction signal, a too rich mixture of fuel and air is prevented.
