I really cannot accept that the forum participants do not understand what this is about. They really think that I'm not going to change anything in Crank mechanism. I repeat, I am not asking how to do this, the question is different. I argue that if engineers succeed in creating an engine in...

If the combustion rate would be ten times less, then I would have been able to get the maximum pressure at the time of rotation of the crankshaft in the 75-80 degrees, as you write, "by designing the combustion chamber, ignition timing and cam timing to produce the peak pressure at the right...

How many percent of the total piston stroke is enough for you? The question is rhetorical. I don't need all this. I want the peak cylinder pressure to be at the moment when the crankshaft shoulder is at 80 degrees, approximately. Then, as in bicycle pedals, the heat loss to the engine walls will...

Thanks for the answer, Nugatory. Since this entire discussion has already been conducted on the Russian forum, I will give some calculations from there. Given: 3000 rpm - 50 rpm / sec Piston stroke 90 mm Flame front speed 30 m / s Downstroke time = 1/100 sec The propagation time of the flame...

I don't know English well, translated using google translate. The working mixture ignites at TDC, and at this point the crankshaft looks up (0 degrees). As the piston descends, the force that the piston needs to travel a certain distance (for example, 1 mm) decreases, up to the moment when the...
