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)
What is a ULEV engine?
The ULEV engine-programmed fuel-injection system is an adaptive type that uses a new 32-bit microprocessor Powertrain Control Module (PCM) with the capability to monitor and control the air-fuel ratio in each individual cylinder. The ULEV Accord engine uses a 1.7-liter, high-efficiency catalyst.
Does a F23A4 have VTEC?
Allegedly, VTEC kicks in [yo] at around 3600 RPM. F23A4: This engine was used in the 1998-2002 Honda Accord ULEV models. It is substantially similar to the F23A1, but features ULEV certification with a slight reduction of power: 148 hp (108 kW) with a maximum torque of 150 lb·ft (203 Nm).
How much horsepower does a 2.3 VTEC have?
The VTEC designation on this engine means that it has Honda’s signature variable-valve-timing. This feature is designed to maximize horsepower at high revolutions-per-minute. The 2.3-liter VTEC produced 150 horsepower at 5,700 rpm.
What is the difference between ULEV and PZEV?
ULEV: Ultra-Low Emission Vehicles. PZEV: Partial Zero Emission Vehicle. PZEVs meet SULEV tailpipe emission standards, have zero evaporative emissions and a 15-year/150,000 mile warranty.
What does sulev mean in Honda Accord?
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 is the best car for low emissions?
Best cars with low CO2 emissions
- Audi A4.
- Ford Focus.
- Hyundai Ioniq.
- Mercedes-Benz A-Class.
- Nissan Qashqai.
- Citroen Grand C4 SpaceTourer.
- Skoda Superb Estate.
- Toyota CH-R.
What cars are ULEV?
ULEV technologies ULEVs include pure electric vehicles, electric range-extender vehicles, and plug-in hybrids (PHEVs). Plug-in hybrids (PHEVs) feature an electric motor powered by a small battery, and a petrol or diesel engine.
What does a VTEC engine do?
The VTEC (Variable Valve Timing & Lift Electronic Control) system uses separate camshaft profiles for low and high-end performance, and the engine computer selects between profiles. The VTEC system essentially combines low-RPM fuel efficiency and stability with high-RPM performance.
Are Honda engines aluminum?
Honda uses aluminum-alloy castings for major components such as the cylinder block, cylinder head and transmission cases.
How much horsepower does a VTEC have?
High-rpm flogging is not required but makes for storming good fun as the 2.0L turbo 4-cyl. pounds out 306 hp before reaching the 7,000-rpm redline. With a specific output of 153 hp/L, this VTEC engine is the most powerful street-legal Honda ever to reach America.
Does PZEV affect gas mileage?
PZEV refers to vehicles with advanced emission controls, but that does not equate with improved fuel efficiency. Hybrid or electric vehicles that meet PZEV standards are sometimes classified as AT-PZEV for Advanced Technology PZEV because emissions are just as clean, but they get much better fuel efficiency.
What’s the difference between the F23A1 and the ULEV?
It is substantially similar to the F23A1, but features ULEV certification with a slight reduction of power: 148 hp (108 kW) with a maximum torque of 150 lb·ft (203 Nm).
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.
What kind of engine does a Honda Accord ULEV use?
F23A4: This engine was used in the 1998-2002 Honda Accord ULEV models. It is substantially similar to the F23A1, but features ULEV certification with a slight reduction of power: 148 hp (108 kW) with a maximum torque of 150 lb·ft (203 Nm).
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.
