Where is the spark plug in an I shape combustion chamber?
In the I-shape combustion chambers, overhead valves are used. A spark plug may be fitted at the centre or at a side of the cylinder head. The engines having this type of combustion chambers are used in high-speed vehicles and racing cars.
Which is combustion chamber projects around the cylinder head?
The t-shape combustion chamber is simple in construction. It projects around the cylinder head. The spark is fitted at the top and valves at the sides. The engines having such combustion chambers have good efficiency. F-shape combustion chamber projects at one side of the cylinder head.
Where are the valves in a spherical combustion chamber?
In the spherical shape combustion chambers, the inlet and exhaust valves are fitted in the cylinder head. A spark plug may be at a side or at the top of the cylinder head. In the I-shape combustion chambers, overhead valves are used. A spark plug may be fitted at the centre or at a side of the cylinder head.
When did the open combustion chamber come out?
In 1969 the open combustion chamber was introduced and it offered better air/fuel flow and a better combustion burn in the chamber.

What kind of combustion chambers does a oval cylinder head have?
The oval port head has 110-cc chambers, and the rectangular port head comes with 118-cc chambers. 98-cc closed combustion chambers with open 118-cc combustion chambers. Note the lazy-D shape of the chambers.
How are the walls of a combustion chamber made?
Chambers operating below about 1000 psia usually use cold-formed stainless steel or nickel alloy tubes which are furnace-brazed together to form the chamber walls ( Fig. 2 ); this assembly is then overwrapped with highly tensilely loaded steel wire or steel bands to carry the chamber-pressure-induced hoop stresses.
How big are the combustion chambers on a Cathedral Port?
After running the 317, 0821, and AFR 245 on the flow bench, we took the opportunity to measure the combustion chambers. The chamber sizes varied from a low of 64 cc for the cathedral-port AFR 245s, 70 cc for the stock LS3 heads, and a high of 73 cc for the 317 heads.
