Abstract
The present invention relates to internal combustion engines. More particularly, the present invention relates to an arrangement whereby internal combustion engines can be operated more efficiently at higher compression pressures. Aspects and/or embodiments seek to provide a method and/or apparatus and/or system for using very high compression ratios in internal combustion engines while preventing damage from pinking or knocking.
Claims20
A method of controlling a throttle for an internal combustion engine, the internal combustion engine operable to compress an ingested fuel air mixture, the method comprising the steps of:
- receiving a throttle signal to open the throttle to a first position;
- in response to receiving the throttle signal, making a determination, without the throttle signal being used to open the throttle to the first position, as to whether opening the throttle to the first position will cause damage to the internal combustion engine, the determination comprising assessing whether the throttle being opened to the first position will cause the ingested fuel air mixture to exceed a predetermined pressure threshold that will cause damage to the internal combustion engine;
- and
- in response to making the determination that opening the throttle to the first position will cause damage to the internal combustion engine, modifying the throttle signal to open the throttle to a second position, the second position of the throttle having been determined to open the throttle to a position that will not cause damage to the internal combustion engine.
A control system operable to modify a throttle signal for an internal combustion engine, the control system operable to modify the throttle signal by:
- receiving a throttle signal to open the throttle to a first position;
- in response to receiving the throttle signal, making a determination, without the throttle signal being used to open the throttle to the first position, as to whether opening the throttle to the first position will cause damage to the internal combustion engine, the determination comprising assessing whether the throttle being opened to the first position will cause the ingested fuel air mixture to exceed a predetermined pressure threshold that will cause damage to the internal combustion engine;
- and
- in response to making the determination that opening the throttle to the first position will cause damage to the internal combustion engine, modifying the throttle signal to open the throttle to a second position the second position of the throttle having been determined to open the throttle to a position that will not cause damage to the internal combustion engine.
A throttle assembly for use with an internal combustion engine, the throttle assembly comprising:
- a throttle and a stop, the stop operable to restrict a maximum opening position of the throttle to a predetermined opening position wherein the predetermined opening position is less than the maximum opening position;
- and
- a controller operable to:
- receive a throttle signal to open the throttle to a first position;
- in response to receiving the throttle signal, make a determination, without the throttle signal being used to open the throttle to the first position, as to whether opening the throttle to the first position will cause damage to the internal combustion engine, the determination comprising assessing whether the throttle being opened to the first position will cause the ingested fuel air mixture to exceed a predetermined pressure threshold that will cause damage to the internal combustion engine;
- and
- in response to making the determination that opening the throttle to the first position will cause damage to the internal combustion engine, modifying the throttle signal to open the throttle to the predetermined opening position.
