A valve arrangement in the cylinder head where the valves are at an angle to the cylinder bore. Canting the valves can make for a straighter path for air to flow into and out of the intake and exhaust ports. The area of an engine in which the air/fuel mixture is burnt.
There are lighters out there designed to burn up to 2500 degrees Celsius, so it is certainly possible to find one that is up to the task if you have a project that involves melting glass. One reason that most lighters will not melt glass is that they are simply not hot enough.
- Do not ignite butane lighter for about 2 - 3 minutes until the butane gas in the gas tank reaches room temperature. - Turn the valve in 1/4 turns counter-clockwise. After each 1/4 turn, try to ignite the lighter until you get the desired flame intensity. Hold butane lighter away from face when igniting. If the flame height adjuster is turned up too high, the lighter will not ignite and you will hear a hissing sound. If this happens, please lower the adjuster by turning clockwise.
