Running rings around opponents up to where we suffered an engine knock
and the Mighty Gor Mahia got knocked off the continental competition was no mean achievement by any standards.
In a situation where the injectors do not get enough supplies, it could cause engine knock
. Replace it with a new filter to keep the fuel flowing into the engine efficiently.
The quality of the fuel in regard to preventing engine knock
is measured by the octane value or RON of the fuel.
However, a new devastating knock named superknock, which is much different from traditional gasoline engine knock
combustion and whose instantaneous in-cylinder pressure can reach above 200 bars, has become a main obstacle for increasing GDI engine power density.
The influence of environmental temperature on self-ignition is evidenced in Figure 6, where upon increasing environmental temperature, the ignition point temperature increases, hence, if the fuel self-ignition temperature is reached, the engine knock
Higher octane ratings in fuel are important for high performance engines to minimize engine knock
. Renewable hydrocarbons like isooctene can directly replace petroleum-based hydrocarbons without any compromise of performance.
Ricardo's mix of practical expertise and acute experimental observation gave him a formidable knowledge of subjects such as engine knock
and pre-ignition, about which most others knew little at that time.
"We asked automotive firms what their toughest challenges were in measurement and they said that detecting engine knock
was the hardest," Downes says.
