Sentences with phrase «exhaust stroke»

Yep, it doesn't matter if you're on exhaust stroke TDC or compression stroke TDC for the piston's position relative to the spark plug.

With high - performance camshaft timing, exhaust valves in different cylinders can be open at the same time, overlapping at the end of the power stroke in one cylinder and the end of exhaust stroke in another.

It utilizes what is known as a wasted spark system, the spark is fired off on TDC compression and TDC exhaust strokes.

Successive splits near 32 seconds sent Meagher into the final 50.69 behind her record pace, but not to worry; she has built her endurance with non-stop butterfly workouts of as long as 1,600 meters, an incredible distance over which to sustain swimming's most exhausting stroke.

In this example, that same 60 PSI also remains in the cylinder for the entire exhaust stroke (exhaust valve open) and exerts 60 PSI on the piston top to resist its upward movement.

If we open the intake stroke as well (overlap) at the end of the exhaust stroke we end up using the momentum of the exhaust to suck in air from the intake port!

In other words, for TDC on the exhaust stroke, is the piston still X inches from the plug on both strokes, or is it located at the bottom of the motor at TDC on exhaust?

This is helpful +1, but I'm still having trouble picturing this in my mind... So for TDC on the exhaust stroke, is the # 1 piston physically located in the same distance from the plug as it would be in TDC of the compression stroke?

The exhaust valve opens at BDC and stays open during the exhaust stroke, and potentially stays open until the start of the intake stroke.

The voltage needed to fire the exhaust stroke plug is about 2kV according to what I've read.

My ignition system is wasted spark, so it has to fire two plugs at once, one on the compression stroke and one on the exhaust stroke.

An interesting aspect is that older fuel injection systems actually would use most of the intake stroke, and the exhaust stroke, to deliver the correct amount of fuel.

Optimum valve control strategies during engine warm - up and internal Exhaust Gas Recirculation, realized by reopening the intake valves during the exhaust stroke, result in emissions reduction ranging from 40 % for HC / CO to 60 % for NOx; and

Exhaust manifolds remove exhaust gas during the exhaust stroke.

The retained exhaust gasses tend to be very rich in un-burnt Hydrocarbons, as they typically come from crevice volumes that are expelled at the end of the exhaust stroke.

Ignition of fuel, power stroke, and exhaust stroke.

For example, at the start of the intake stroke of cylinder one and when both the intake and exhaust valves of cylinder one are open (valve overlap period), cylinder three already starts its exhaust stroke with the exhaust valve open.

For example, at the start of the intake stroke of cylinder one and when both the intake and exhaust valves are open (valve overlap period), cylinder three already begins its exhaust stroke with an open exhaust valve.

That explosion drives the piston downward, turning the crankshaft, and opening the exhaust valve on the exhaust stroke.
