What Are the Different Types of Alternate Fuels?
Energy is an important material foundation on which human beings depend for their survival and development. The lack of energy, especially petroleum resources, and the deterioration of the global environment have become two major problems in the development of today's world society. In order to alleviate the contradiction between China s lack of petroleum resources and demand, and to achieve China s long-term sustainable economic development and environmental protection, it is necessary to develop internal combustion engines to replace clean fuels to partially replace petroleum-based fuels, namely gasoline and diesel.

Requirements for alternative fuels
- There are many substances that can be used as fuel for internal combustion engines. The following points should be considered when selecting:
- (1) Whether the resources are abundant and stable and it is best to be able to regenerate.
- (2) The production process is simple, the original investment is not large, and the fuel cost is low.
- (3) Good compatibility with the existing internal combustion engine technology system and infrastructure.
- (4) The production process is environmentally friendly.
- (5) Can significantly improve exhaust emissions from internal combustion engines.
- (6) It has little effect on the power and economy of the internal combustion engine, and can be improved better.
- According to the current use of alternative fuels worldwide, they can be generally divided into three categories: oxygen-containing fuels such as alcohols, ethers, and esters (mainly including methanol, ethanol, dimethyl ether, and biodiesel made from vegetable oils) ; Synthetic oil (refers to liquid fuel oil produced from coal, natural gas or biomass); Gas fuel (refers to natural gas, liquefied petroleum gas, hydrogen, coal bed gas, biogas, etc.).
Parameters of alternative fuels
- In the selection of alternative fuels, the main physical and chemical performance parameters of alternative fuels must be carefully analyzed and compared with gasoline or diesel to carry out the necessary technical transformation of the original engine. Particularly important parameters are:
- (1) Oxygen content, self-ignition temperature, octane number (spark ignition engine), cetane number (compression-ignition engine), mutual solubility and stability with gasoline or diesel fuel (when used as a mixed fuel) of alternative fuels.
- (2) Low heating value, stoichiometric air-fuel ratio.
- (3) Viscosity and lubricity of fuel.
- (4) Compatibility with elastic sealing materials.
- (5) The toxicity of the fuel itself, ie the fuel emissions.
- (6) Biodegradability of the fuel itself [1] .
