Explanation of template parameters

All dimensioned parameters should be written in both imperial units and metric units. For American and British designs, the format is imperial (metric). For all others, it is metric (imperial).

type = Engine in a nutshell, #-cylinder turbo/supercharged air/liquid-cooled inline/rotary/V-# piston aircraft engine
designer = Who
bore = Diameter of each cylinder, in (mm)
stroke = Distance the piston travels inside the cylinder, in (mm)
displacement = Total volume of the engine, in³ (L)
length = Length of the engine, in (mm)
diameter = Diameter or width of the engine, in (mm)
width = Width of the engine, in (mm)
height = Height of the engine, in (mm)
weight = Dry weight of the engine (without oil, coolant, etc.), lb (kg)
valvetrain = Description of valves, including number of intake/exhaust valves per cylinder and valve operation (camshaft/pushrod, OHV/OHC), for example two pushrod-actuated valves per cylinder with sodium-cooled exhaust valve or overhead camshaft-actuated, two intake and two exhaust valves per cylinder, sodium-cooled exhaust valve stems
supercharger = Description of the supercharger, leave blank if not installed, for example two-speed two-stage, boost pressure automatically linked to the throttle, water-air aftercooler installed between the second stage and the engine
turbocharger = Description of the turbocharger, leave blank if not installed.
fuelsystem = Description of the fuel system (carbutered/fuel injected, etc.), for example twin-choke updraft carburetor with automatic mixture control
fueltype = Fuel type, octane rating
oilsystem = Description of the oil system, for example dry sump with one pressure pump and two scavenge pumps
coolingsystem = Description of the cooling system, for example 70% water and 30% ethylene glycol coolant mixture, pressurized. At the very least say if the engine was air- or liquid-cooled.
reduction_gear If there's one, give the ratio or otherwise describe it
power = Power output, hp (kW) at # rpm
specpower = Specific power, power output divided by engine displacement; hp/in³ or kW/l
compression = Compression ratio, #:1
fuelcon = Fuel consumption, US gal/h (L/h) or lb/h (kg/h)
specfuelcon = Specific fuel consumption lb/(hp·h) (kg/(kW·h))
oilcon = Oil consumption US gal/h (L/h) or lb/h (kg/h)
power/weight = Power-to-weight ratio, calculated by dividing engine power by engine weight, hp/lb (kW/kg)
