What does ULEV VTEC mean?
Emissions. EX and LX engines qualify as California LEV (Low-Emission Vehicles) EX with automatic transmission qualifies as ULEV (Ultra-Low Emission Vehicle) in California. Stratified-charge VTEC. Electronically controlled EGR (Exhaust Gas Recirculation)
Why does the accord engine use ULEV fuel injection?
The ULEV engine PCM can also compensate for mixture inaccuracies caused by fuel-droplet adhesion to the intake port walls during cold start-up (a major reason for a high level of unburned hydrocarbons during the warm-up cycle). The ULEV fuel-injection system also utilizes the precise EGR control provided by the Accord engine’s electronic EGR valve.
Is the Honda Accord EX an ultra low emission vehicle?
In California, the Accord EX with the available automatic transmission will produce less than 0.003 grams per mile of NMOG, qualifying it as the first gasoline-powered vehicle to reach ULEV (Ultra-Low Emission Vehicle) status. Allegedly, VTEC kicks in [yo] at around 3600 RPM.
What kind of engine does the Accord EX use?
The ULEV (Ultra-Low Emission) engine used on the Accord EX model with automatic transmission uses several new technologies to achieve its remarkably low emissions output.
What’s the difference between VTEC and ULEV engine?
In addition to the electronic EGR control and lean combustion afforded by the VTEC swirl-combustion process, the ULEV engine uses precise air-fuel control made possible by a Linear Air-Fuel sensor, secondary oxygen sensor, high-performance catalyst and new 32-bit fuel-injection microprocessor.
