  2. Cold inflation pressure - Wikipedia

    en.wikipedia.org/wiki/Cold_inflation_pressure

    Cold inflation pressure is the inflation pressure of tires as measured before a car is driven and the tires warmed up. Recommended cold inflation pressure is displayed in the owner's manual and on the Tire Information Placard attached to the vehicle door edge , pillar , glovebox door or fuel filler flap .

  3. Ideal gas law - Wikipedia

    en.wikipedia.org/wiki/Ideal_gas_law

    The pressure and temperature of the gas are directly proportional: As temperature increases, the pressure of the propane gas increases by the same factor. A simple consequence of this proportionality is that on a hot summer day, the propane tank pressure will be elevated, and thus propane tanks must be rated to withstand such increases in pressure.

  4. Liquefied petroleum gas - Wikipedia

    en.wikipedia.org/wiki/Liquefied_petroleum_gas

    LPG is composed mainly of propane and butane, while natural gas is composed of the lighter methane and ethane. LPG, vaporised and at atmospheric pressure, has a higher calorific value (46 MJ/m 3 equivalent to 12.8 kWh/m 3) than natural gas (methane) (38 MJ/m 3 equivalent to 10.6 kWh/m 3), which means that LPG cannot simply be substituted for ...

    The cost to convert a vehicle to propane in Canada is approximately CA$4,000 to CA$6,000 for the current vapour or liquid fuel injected technology, and fleet users can expect a payback on the conversion cost within a year. Converting a vehicle to propane is approximately half the cost of converting a vehicle to natural gas in Canada.

    en.wikipedia.org/wiki/Snow_tire

    The pin should protrude at least 1 millimetre (0.04 in) for the tire to function properly. [8] Snow tires do not eliminate skidding on ice and snow, but they greatly reduce risks. [9] Studdable tires are manufactured with molded holes on the rubber tire tread. Usually, there are 80 to 100 molded holes per tire for stud insertion.
