Alternative car fuels

Heating value is the amount of heat released during a combustion of some fuel. It is sometimes called a calorific value. There are two ways to describe this amount of heat. (more…)

Vegetable oil can be used as an alternative fuel for diesel engines. In this article I’ll describe how to use straigh or waste vegetable oil for your compression ignition engine.

Vegetable oil can be used as an alternative fuel for your car in one of three ways:

• after chemical altering to biodiesel,
• mixed with petrodiesel,
• as single fuel. (more…)

Diesel engines, called also compression ignition engines, are internal combustion engines operating on Diesel cycle. The principles of this cycle as well as first diesel engine were discovered in 1890s by Rudolf Diesel.

The combustion in diesel engine is started when the pressure in combustion chamber exceeds ignition point of fuel injected to the chamber. During the compression stroke, the air inside the combustion chamber is compressed and because of that it increases it’s temperature. On a proper timing fuel is injected to the combustion chamber and ignites from the hot air inside. (more…)

Biofuels are all the fuels that are made of biomass (all biological matter, produced by living organisms). They are a renewable energy source, contrary to fossil fuels like oil, natural gas, coal or uranium. Some scientists use term biofuel only referring to fuels that in more than 80% (volumetric) are made of biomass harvested 10 years prior to producing that fuel. (more…)

Biodiesel is an alternative fuel for diesel (compression ignition) engines. It is made of renewable, biodegradable materials, e.g. animal fats and vegetable oils.

In contrary to petroleum based diesel fuel, biodiesel is biodegradable non-toxic fuel. Its usage reduces emissions of many toxic substances that occur when standard diesel fuel is used. It can be used in almost every engine or device that works on petroleum diesel. (more…)

Wood gas (holzgas in german) is the product of wood gasification. It consists of combustible gases such as carbon monoxide, hydrogen, methane and inert gases - nitrogen, carbon dioxide and water vapor. The composition of the wood gas depends on many factors, e.g. temperature inside the gasifier, moisture content of fuel gasified etc. (more…)
