The volume displacement of an engine is a fairly simple measurement and engne builders cc their engines to ensure each cylinder has equal volume which would promote balance when running. Whether it is measured in liters (L), cubic centimeters (cc) or in cubic inches (ci) makes no difference. In Europe it has always been cc and L, even for the big, powerful engines such as Ferrari and Lamborghini. In the United States we had cubic inches but because we are trying to come up with a globally recognized measuring system, we've chosen to adopt cc or L instead of ci.Here is how volume displacement is measured in engines:With the head(s) off the engine, each piston would be measured at the bottom of it's stroke. A thick acrylic panel would be placed over the engine block in place of the head. Over each piston bore there would be a hole to introduce water. With the piston in the fully down position, the volume from the top of the piston to the top of the block would be accurately measured by filling the volume with water until there is no air bubbles under the plastic. The amount of water it takes to fill is the volume of that particular cylinder. Do that to all cylinders and add up the results.We do the same procedure to the heads to determine the combustion chamber volume. With the valves fully shut, introduce water until no air bubbles exist. Add the volume to that cylinder's volume already obtained and you will have the total capacity of that cylinder. Add up all total capacities and you would have the volume displacement of that engine.The engine would run one heck of a lot better if each and every piston/combustion chamber volume was exactly the same. Then, with exact metering of a fuel/air mixture, the power developed would be the same for each cylinder and the engine would run smooth and powerful.The 1.14 L (~17.39cc/cylinder) engine is only 69.56707 cubic inches so we aren't talking about too much power here but modern 4 banger engines have been found to take that minute amount of power and get a vehicle to act pretty peppy. With gas prices nearing $3/gal, we need real performance and not just overcoming obstacles with brute force.
