Isn’t this much like how Diesel engines work? They compress air first to heat it to the point that when mixed with fuel it spontaneously ignites. Maybe glow plugs can make a comeback.
It sounds somewhat similar to a supercharged two-stroke design like the formerly very popular Detroit Diesels (8V71, 6V92TA, for example). None of those engines were very efficient though.
Diesel engines are based off a south Pacific people's invention who used a bamboo tube with piston to ignite a sliver of wood. Rudolph used it as inspiration for his engine design.
He also intended the fuel for it to be peanut oil or canola oil a crop farmers could grow for their tractors.
Glow plugs are still here sort of although now a heating grid. My diesel truck has it to pre-heat the air to make starting easier.
In the diesel case, fuel is immediately at its auto-ignition temperature when introduced. In this, the air-fuel mixture is heated until it reaches its auto-ignition temperature.
Also, glow plugs are only used for starting.
