Intake valve must be open
Intake valves.
A car engine can be classified based on the number of cylinders it has. It could be a 4 cylinder, 6 cylinder, 8 cylinder, 10 cylinder, or 12 cylinder (the last two engines are mainly used in exotic cars). There are also rotary engines, electric engines, natural gas engines and hybrid (electric/gas) engines. Each of these has subcategories as in the most common piston engines listed above.
Intake valve must be open to allow atomized fuel mixture to enter cylinder--than all valves are closed during compression stroke 4- stroke engine 1) intake valve open to allow fuel mixture to enter cylinder 2) compression stroke all valves closed 3) ignition stroke mixture is ignited by spark from spark plugs 4) exhaust stroke--exhaust valve is open to allow residue to escape
Not all 4 cylinder engines are interference. When the timing belt breaks in an interference engine the valves can cause serious damage.
Both the four cylinder and six cylinder engines are non-interference so if the timing belt breaks there will be no damage to the valves. The 1993-2001 four cylinder engines all use the same block and heads as do the six cylinder engines.

It is the cylinder closest to the belt side of the engine.
all Honda civics have 4 cylinder engines
Yes, they all have inline 6 cylinder engines
No , the 1.9 liter 4 cylinder , the 2.4 liter 5 cylinder , and the 2.5 liter 5 cylinder engines in a 2004 Volvo S40 are not interference engines
Depending on which engine you have and if the engine is a dohc engine four cylinder engines have two valves per cylinder totaling eight, unless it is a dohc then it has four valves per cylinder then it would have sixteen, the same holds true for the six cylinder engines with single cam engines having twelve and duel overhead cam engines having twenty four
