A method of determining fuel quality in an internal combustion engine comprises the steps of: a) sampling a signal representative of the revolution speed of said engine during a sampling window, thereby obtaining an array of samples; and b) computing a Fou...

The method involves determining a crank angle value at which maximum pressure of a cylinder (12) occurs in a combustion chamber (14), during combustion of a fuel mixture. The value is compared with a maximum angle threshold value representing an abnormal c...

The invention relates to a method for improving combustion in a combustion chamber of a combustion engine. The method comprises the first step of receiving a measured air-to-fuel ratio value. Further, the method comprises the step of receiving at least one...
