Because air outside is generally cooler than where a heat causing engine is. The combustion chamber inside super heats the air
The power stroke * intake / compression / power / exhaust
Valve overlap occurs in a four-stroke engine at the end of the Exhaust stroke and at the beginning of the Induction stroke; and is when both the exhaust and inlet valves are open at the same time. At the end of the Exhaust stroke, the Exhaust valve is closing and the Inlet valve is starting to open in preparation for the induction of fuel and air into the cylinder. It is common knowledge that in vehicles that cannot alter the valve timing, the Inlet valve opens approx 6 degrees before top-dead-centre and the Exhaust valve closes at 9 degrees after top-dead-centre

Increasing the speed of the Suzuki Raider R150 is SERIOUS BUSINESS, as it is already one of the fastest under-bone motorcycles in its class. But it CAN be made to go faster, with a few modifications: to the exhaust system and the engine's ports. I MUST STRESS THIS: Engine modifications of this sort are best done by Licensed SUZUKI RACING TEAM Mechanics. As it is easy to DIY (Do It Yourself), it is also easier to waste a perfectly good motorbike with inexperience and misinformation: DO NOT ATTEMPT TO MODIFY AN ENGINE IF YOU ARE NOT QUALIFIED TO DO SO. Neither should you have this done by a mechanic who is NOT experienced with Suzuki Motorcycles. Still interested? Read on... 1.To start with, changing the exhaust pipe to a "CALIBRATED HEADER"- more commonly called an "open pipe" adds a bit more power, and thus, speed. A "CALIBRATED HEADER" is an exhaust pipe that is DESIGNED TO MAXIMIZE EXHAUST OUTPUT without compromising BACK PRESSURE or RETURN PRESSURE to the exhaust port valves. Plainly speaking, the exhaust pipe should be made by a company that is known to have designed pipes for the Raider R150 using SCIENTIFIC METHODS in auto mechanics. A pipe that is not designed this way will only add more noise to your Raider than power and speed. 2. Get a reputable EXPERIENCED mechanic to POLISH THE PORTS (Intake and Exhaust) of your Raider engine. This will involve SHAVING and SMOOTHING the insides of the ports so that the gasoline and air mixture enter the engine in greater amounts and the exhaust is expelled more rapidly. Doing too much of this is IRREVERSIBLE and will do more harm to the engine than good. 3. Purchase RACING CAMS- these will open and close the intake and exhaust valves more efficiently and will result in better acceleration and thus, speed. Have these installed by a Licensed Suzuki Motorcycle Mechanic or your valves may break (very expensive repair) or your engine may blow apart (MORE expensive repair). Once done perfectly, WEAR YOUR HELMET AND PROTECTIVE GEAR, go out to a race-track and test the modifications BEFORE you drive your bike on populated roads. There are other modifications you can do to make your Suzuki Raider R150 go even faster, but...if you're looking for more speed, maybe you should buy yourself a bike with a bigger engine AND a reputation for speed.

The intake valve is bigger.
Exhaust fan is only use for exhaust the old air, while ventilation fan is use for both purpose intake and exhaust.
The intake manifold is where the air and fuel mix and enter the engine. The exhaust manifold is where unspent gas and air exit the engine. In other words the intake manifold is where the engine breathes in and the exhaust manifold is how the engine exhales out.
DOHC - Dual Overhead Cam. This means that there is an intake and an exhaust cam, allowing the valves to move differently for the intake and exhaust. SOHC uses a single cam with more lobes
the diffence is the intake manifold and exhaust manifolds are slitly bigger
8v.....of course.acually it is the number of valves in the head . An 8v has 2 per cylinder( one intake and one exhaust) a 16v has 4 valves per( 2 intake and 2 exhaust).
The difference is in the size of the engine. Specifically in the intake and exhaust ports. The bore and stroke of the crank and pistons and the size of the combustion chambers.
No the lifters themselves are all the same. I recommend lightweight pushrods though if you can get them and stay with hydraulic.
as intake air temperature increases it lead to decreas in i.c engine efficiency. as engine efficiency is ratio of difference in intake and outlet temperature to intake temperature.
Your exhaust lines up with exhaust pipes ,your intake lines up with your intake runners.
The exhaust lifters will line up with the exhaust manifolds,Remove the valve cover if your working on a V8 and the valve that lines up with the exhaust port will be the exhaust valve,If it is a Chevy V8 they will be from standing in front of the car exhaust,intake,intake,exhaust,exhaust,intake,intake,exhaust.
look at the head with the valve cover off find where the exhaust manifold goes in tha is the exhaust valve or looking at the valves the first one is exhaust then intake then intake ,exhaust,exhaust,intake,intake,exhaust if you have the head off i think the intake valves are bigger than the exhaust
