What does SULEV mean for Honda?
Super ultra-low emissions vehicle
Super ultra-low emissions vehicle (SULEV) is a U.S. classification for passenger vehicle emissions. The classification is based on producing 90% fewer emissions than the average gasoline-powered vehicle.
What Hondas have DOHC?
The DOHC/VTEC engine was subsequently adapted for use in the NSX, Accord and Civic. Following the SOHC/VTEC engine, and then the VTEC-E in 1991, this technology evolved into the three-stage VTEC engine introduced in 1995, which demonstrated an even greater degree of efficiency in output control.
How do I know if my car is SULEV?
You can check the above-described label under the hood should you want to confirm. If it says it’s SULEV, then it’s the N51 engine, and if it says LEV, then it’s the N52. There are other ways, too, including looking at your BMW vehicle identification number (VIN).
Which engine has VTEC?
Honda continued to improve the original VTEC system, which has now evolved into the Honda i-VTEC® (intelligent-VTEC). This technology was first available in 2001 and most Honda 4-cylinder vehicles used i-VTEC® by 2002. The i-VTEC® system combines the original VTEC with Honda’s VTC (Variable Timing Control).
What does SULEV warranty cover?
If any emission-related part on your vehicle is defective, the part will be repaired or replaced by BMWNA. This is your emission control system DEFECTS WARRANTY. I interpret this as a two-part warranty, one that covers the individual parts in the SULEV parts list, and one that covers a failed emissions test.
How long is SULEV warranty?
Here’s the good news: When BMW sold that 128i SULEV in California, it not only met emissions standards when it was new, it was guaranteed to meet those standards for “the life of the car.” There’s a fifteen-year, 150,000-mile warranty on a whole list of emissions-related parts.
Why was the Honda VTEC engine added to the car?
The added boost helped improve the engine’s low end punch, but VTEC proved to still be a valuable addition when the revs climbed, with the engine having a high degree of poise in a region where other turbocharged units simply ran out of steam.
What does the VTEC system do at 5000 rpm?
As engine rpm builds past 5000 rpm, the VTEC system transitions to a high-lift, long-duration intake cam profile for superior high-rpm engine power. The “intelligent” portion of the system is its ability to continuously vary the timing of the intake cam relative to that of the exhaust camshaft.
What’s the difference between Honda Accord PZEV and ULEV-2?
The principal differences between the PZEV Accord and the ULEV-2 version sold in all states are single exhaust valve operation at low rpm, special dual-probe spark plugs and remapped Powertrain Control Module (PCM) programming, in addition to the near-zero evaporative emissions equipment.
