What is the difference between ULEV and VTEC?

What is the difference between ULEV and VTEC?

ULEV has to do with the emission of your vehicle. SOHC VTEC is the engine technology that your vehicle utilizes.

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.

Does VTEC give you more power?

Vtec is simply the ability to switch between two cam profiles. It doesn’t give you power, it doesn’t make your powerband larger or broader (at this point), it doesn’t allow you to rev higher. It simply is a way to switch between a street profile and a performance profile.

What is a ULEV engine?

An ultra-low-emission vehicle (ULEV) is a motor vehicle that emits extremely low levels of motor vehicle emissions compared to other vehicles.

What does ULEV stand for?

Ultra low emission vehicle (ULEV) is the term used to describe any vehicle that: uses low carbon technologies. emits less than 75g of CO2/km from the tailpipe.

What vehicles are ULEV?

An Ultra-Low Emission Vehicle (ULEV) is a low emission car or van that emits 75g/km CO2 or less, based on the NEDC test. ULEVs include pure electric vehicles, electric range-extender vehicles, and plug-in hybrids (PHEVs).

Does VTEC make a car faster?

Honda developed its Variable Valve Timing & Lift Electronic Control (VTEC) technology to make its cars quicker, more efficient, and more enjoyable to drive overall.

What is the difference between sulev and ULEV?

ULEV: Ultra-Low Emission Vehicles. ULEVs are cleaner than LEV certified vehicles. SULEV: Super Ultra-Low Emission Vehicle. SULEVs are cleaner than ULEV certified vehicles.

What is the difference between SULEV and ULEV?

How do I know if my car is ULEV?

How do I know if my vehicle is an ULEV?

  1. If your vehicle is fully electric then it is an ULEV.
  2. If your vehicle has a pure petrol or diesel engine, then it is not an ULEV.

Which is better i-VTEC or VTEC?

i-VTEC (intelligent Variable Valve Timing and Lift Electronic Control) was introduced in 2002 to the North American market. Thus, the i-VTEC system provides all the benefits of the traditional VTEC design’s high-end open throttle power, while providing better engine operation at low and partial throttle. …

What’s the difference between a VTEC and VTEC-E?

VTEC-E is quite different from the standard VTEC, because Honda did not design it for optimal horsepower at high RPMs, instead they designed for optimal fuel efficiency at low RPMs. VTEC-E does this by effectively forcing the engine to run as a 12 valve engine instead of its normal 16 valves.

What kind of exhaust system does the ULEV engine use?

The ULEV engine uses a rotary air-control valve that also controls the Air-Assist Injection system, in place of the electric air-control valve and fast-idle valve used in the previous Accord. The exhaust system solves the problem of passing combustion heat to the catalyst as soon as possible.

What’s the difference between VTEC and iVTEC in a K20A3?

K20A3: The K20A3 iVTEC system is far different than the A2’s system. It is VTEC-E with VTC, and really shouldn’t even be classified as iVTEC. At low RPM only one intake valve opens, which decreases fuel consumption, then at 2,200 rpm, it engages the second intake valve, allowing it to operate like a normal 16 valve engine.

What kind of engine does Honda use VTEC for?

Honda also applied the system to SOHC (single overhead camshaft) engines such as the D-Series and J-Series Engines, which share a common camshaft for both intake and exhaust valves. The trade-off was that Honda’s SOHC engines benefited from the VTEC mechanism only on the intake valves.
