If you can’t get or afford the price of gas and your fuel gauge looks like this often, you might want to try some different ideas to save gas or improve mileage. First always make sure your car is running as good as it can. This can be done by performing a tune up which generally consists of spark plugs, plug wires, air filter, fuel filter, and distributor cap and rotor if applicable. If you have a fuel injected car and the check engine light is on you may have a problem that is costing you a lot of extra fuel. The car will then be running in a “limp” mode which usually consists of using extra fuel for the safety of the engine. Things such as the oxygen sensor (o2) will cause the engine to use extra gas also.
Small engines can be purchased for many self hobby types. Places like Northern Tool are great for small engines anywhere between one horsepower to 23 horsepower engines. These engines are purchased for many projects like water pumps, go carts, homemade generators, log splitters and various other projects. Pay attention to your project before purchasing an engine. Some projects require verticle shaft engines where others need horizontal shaft engines. The engine configuration generally will not interchange with the others. You will probably need accessories also to couple the engine to whatever drive system you use. Generally the same store, such as Northern Tools, will have sprockets, and drive shaft coupling parts to connect to whatever parts and components that need to be driven. If you plan to make a go cart briggs and stratton and tecumseh both have race cart series. It would make sense to use the same engine so that you have all the same aftermarket parts available to you. If you plan to build a generator make sure the engine has a good governing system to control the engine rpms. A generator engine should be run around 3600 rpms to keep the cycles at 60 hertz as regular ac power.
It is relatively easy to convert a small gasoline engine to propane or natural gas. There are lpg/propane kits designed to make this conversion easy. They generally consist of a simple plate that sits between the carb and the engine. A regulator is usually attached to regulate the propane going to the spacer plate. The regulator is needed to supply more fuel as the load or power demand increases. Instead of the engine bogging down, the regulator supplies more fuel so the engine makes more power. Propane or lpg is already in a gaseous form, which does not have to vaporize and will not leave carbon deposits. Carbon is bad because it is hard and leaves deposits which cause engine wear. Carbon makes your oil black and breaks the oil down faster. Producing less carbon should dramatically increase an engine’s life. Power and fuel consumption are very similar to using gasoline. The power will vary depending on what engine it is being used on. Mileage will be similar, but could be better than a stock carburetted engine. Propane tanks are usually safe and are very resistant to impact. The tanks will vent if the internal pressure gets too high, for safety. Many people like to convert generators to natural gas/ propane. They use the same source as their home’s fuel source for heat. When the power goes out, they have a limitless supply of fuel without having to refill a generator tank up with gas cans. Conversion kits can be reasonably priced and bought online.
