Sentences with phrase «when less engine»

For example, the shutter will close at highway speeds when less engine cooling is required and aerodynamic drag is most significant; the system will open when the car is hot city driving, traveling up a hill or pulling a trailer.

- Cylinder deactivation: When less engine power is needed, such as in highway driving, the valves and fuel injectors in half the engine cylinders are deactivated.

Whether the shutter is open or closed depends on engine coolant temperature and speed — for example, the shutters open when the car is traveling up a hill, pulling a trailer, or in hot city driving; the shutters close at highway speeds when less engine cooling is required.

Greater turbulent flow makes for a less aerodynamic ride, but it helps cool the engine when passing under the hood.

Those modifications include stop — start (idle - off) systems in which the engine shuts down when the car is stopped during driving; low rolling - resistance tires (which are harder and thus less flat, reducing friction); variable valve timing for engines, which increases gas consumption efficiency; and fuel economy computers or displays to encourage eco-driving, such as such as those in the Toyota Prius, which show miles per gallon averages for that moment, hour, week or month, or when riding downhill, so that drivers are more aware of how their driving impacts fuel efficiency.

«The increase in emissions at lower temperatures is related to a more pronounced cold - start effect,» when a gasoline engine is less efficient because it's not yet warned up and its catalytic converter is not yet on, the study noted.

Yet, the catalyst would still have to work when an engine is started cold and must clean up the exhaust before reaching 150 degrees Celsius, more than 100 degrees Celsius less than current systems.

When savvy users go to a search engine, they know that the more specific their entry, the less browsing through results they'll have to do.

Later, when factory managers first replaced their large steam engines with large electric motors, the new electric motors were less noisy and didn't produce smoke, but they had little impact on productivity.

This also limits the maximum RPM of the engine because there are increased friction losses due to increased speed of the piston at the same RPM when compared to an engine with less stroke.

When we sampled Infiniti's new Q50 Red Sport 400, we were dutifully impressed by the almost instantaneous torque from its new 3.0 - liter twin - turbocharged V - 6 engine and its brilliantly composed chassis, but less so with its intrusive traction - control system.

Because 99 % of the time I will be within these RPM ranges, the engine will be producing more horsepower without a lot of noise or fuss, with better engine longevity - the engine will be producing more power at a lower RPM hence less engine wear, and finally there is more instant acceleration when I need to accelerate without having to change down a gear every time, which I would have to do in the peaky engine.

Admittedly, as the engine doesn't really get going until after 3000rpm it's less of an issue when you're enjoying a quiet road and from about 4500rpm it definitely pulls harder than the standard car.

When pressed on its choice of gas engines, Fisker admitted that few powerplants met the company's specifications (2.0 liters or less, 260 hp or more).

Some engines, especially small engines, have compression release valves so that it's easier to turn the engine when you first start it because there is less compression in the cylinder.

A couple that come to mind are the volume or air / fuel mixture (Why timing is advanced when under less load / higher vacuum) and air / fuel ratio (why timing is pulled when the engine is cold).

There's no doubt that the GT2 loses ground to the 599 in those entry phases - it just doesn't have the same mechanical purchase on the surface — and, of course, its less linear power delivery makes holding a stable throttle position through the turn more difficult, but when you release the steering angle and squeeze the right pedal to the floor, the combination of twin turbochargers and rear - engine traction are imperious.

So if you leave the clutch pedal released, and if the engine power is such that no torque is being applied by the engine, there could in theory be less wear on the synchronizers when disengaging them by moving the shifter to neutral because you can artificially make that amount zero.

The upside of hydraulic clutches are they self adjust, they tend to last a long time, they take up less space in the engine compartment, and when they do fail they tend to fail slowly, usually due to a leak.

I say that because the sound seems about the same when the engine is doing less work.

And even though the engine is moving half a ton more car than when it's bolted to a Volkswagen GTI, the 4000 - pound A5 still weighs 600 pounds less than the BMW, so it's very nimble.

Listen carefully around the brake booster (the large round object more or less in front of the driver in the engine compartment), I suspect that there is a leak that is causing the idle mixture to change, probably too lean as air is being pulled in when the brake is applied.

It's too bad that you can't buy a new car with a rotary engine or one that weighs less than a ton (save for the Smart ForTwo), but when good cars can't be bought in dealerships, they trade in a market that values them as more than cars.

Edit: Coolant in some cars passes through a type of fast idle valve that raises and lowers a plunger (connected to some type of heat reactive wax that closes the airway fully when the coolant is at OT) through a tube that feeds more or less air through the engine raising or lowering its speed.

Now obviously when you accelerate harder, more fuel is being pumped into your engine, but you'll sooner get to that cruising sweet spot where fuel consumption is a lot less.

Common to all variations of the breed is an unmistakable sound that didn't change dramatically when the air - cooled boxer was replaced by the water - cooled engine in late 1997; a less - than - ideal weight distribution combined with a high polar moment of inertia; compromised packaging with little room for luggage; and a driving experience dominated by phenomenal grip and traction — while it lasted.

Porsche say (of course) that the new models are an improvement over the six cylinder cars, but the EU has driven them to smaller turbo engines to save the planet, and Porsche Marketing has driven them into four cylinders to stop the Cayman / Boxster line from stealing 911 sales (why pay so much when you could get a 911 engined Boxster for so much less money)?

The CVT transmission automatically engine brakes when there is no throttle, which then requires the application of more throttle to continue at the same speed (making it less fuel - efficient in the long run).

Now, I know they are very different cars, but for almost # 60,000 less (probably considerably more when you factor in the cost of all those expensive Porsche extras), you can get a Ford Mustang with a brilliant 5 litre V8 engine.

When this is less than what is needed in order for the motor to fire or in some cases higher than normal, you may notice an erratic fluctuation in engine RPMs, hard starting or a lack of power when accelerating as the engine may be starved for fuel if insufficient fuel pressure exists in the fuel sysWhen this is less than what is needed in order for the motor to fire or in some cases higher than normal, you may notice an erratic fluctuation in engine RPMs, hard starting or a lack of power when accelerating as the engine may be starved for fuel if insufficient fuel pressure exists in the fuel syswhen accelerating as the engine may be starved for fuel if insufficient fuel pressure exists in the fuel system.
