Definitions
- spark ignition gasoline engine fuel is injected into the intake port or the combustion chamber, and premixed gas of air fuel mixture is formed. Then the premixed gas is ignited by a spark plug and combusted.
- the fuel is required to have high vaporization and low auto-ignitability characteristics. Since the spark ignition gasoline engine emits nitrogen oxides (NOx), hydrocarbons (HC) and carbon monoxide, a three-way catalyst has been widely used for purifying these emissions. However, an exhaust gas purification system such as a three-way catalyst is only applicable to a range where the air-fuel ratio is in a very narrow range of stoichiometric air-fuel ratio and it is the causes of low thermal efficiency and poor fuel consumption comparing with the compression ignition diesel engine.
- a high temperature combustion region the temperature of which is higher than 2200K, is not locally formed in the cylinder and this is the cause of low NOx emission characteristics (less than 10 ppm by mass) without a reduction catalyst.
- the thermal efficiency and fuel consumption of the homogeneous charge compression ignition engine are equivalent to those of the diesel engine.
- Fig. 5 shows the change in maximum pressure rise rate at Point 3 over 400 cycles.
- Fig. 3 shows the changes in maximum pressure rise rate over 400 cycles at Point 1
- Fig. 4 shows the changes in maximum pressure rise rate over 400 cycles at Point 2
- Fig. 5 shows the changes in maximum pressure rise rate over 400 cycles at Point 3.
- NTL series fuels corresponding to the fuel of the present invention are reduced in maximum pressure rise rate by 20 percent or greater, comparing with PRF series fuels (PRF90, PRF85) when they were used under the same operation conditions (same IMEP, same HTHR CA50). Further, when the fuels other than Comparative Example 1 (NDB fuel, NMP fuel) are compared with the NTL series fuels of Example 1, none of the other fuels can reduce the maximum pressure rise rate as much as the fuels of Example 1.
- NTL series fuels (NTL75, NTL80, NTL85) according to the present invention exhibited an increase by 28 to 113 percent in indicated mean effective pressure, compared with comparative fuels (PRF series fuels, NDB series fuels, NMP series fuels, NCP series fuels) under the same maximum pressure rise rate condition.
- PRF series fuels NDB series fuels
- NMP series fuels NCP series fuels
- Figs. 7 , 9 and 11 this is because the fuel of the present invention prolongs combustion period by utilizing difference in ignition temperature between a component containing mainly a paraffinic fuel and a component containing mainly an aromatic fuel so as to avoid the rapid combustion of the fuel and thus the more fuel can be combusted under the same maximum pressure rise rate, thereby increasing the heat release rate.
