If youíve been paying attention, youíve noticed that New York vehicles are getting more and more powerful and at the same time are getting better and better gas mileage. Much of thatís because of better transmissions. To get a understanding of why that is, letís turn to gear experts Ė Taberg bicyclists.
A cyclistís cadence is the number of times per minute he or she pedals. Their ideal pedal speed is the zone where they can most efficiently generate power over a sustained period of time. The experienced cyclist uses his gears to keep his pedal speed in the ideal zone whether heís climbing a steep Rome hill, cruising on a flat stretch or killing a downhill.
Look at how it works: if you have a 1-speed bike, you really have to pump hard to get up to speed. And your top speed is limited by how fast as you can pedal. And if youíve got a hill to climb Ė forget about it.
Now letís add a couple of gears: one lower and another one higher. With the lower first gear, you can get up to your ideal pedal speed quicker. When you shift to second, your pedal speed drops below ideal for a while as you work to get back to peak efficiency. Same thing happens when you shift to third, but now you can go much faster than you could with a 1-speed bike using the same effort.
Add more gears and you can see that itís much easier to maintain ideal pedal speed. The result, quicker starts, better hill climbing, higher top speed and, most of all, a lot less fatigue for the rider.
Like a cyclist, every car engine has an ideal engine speed called its power band. When an engine is running in that zone, it can make power very efficiently. Itís the transmissionís job to keep the engine in the power band over a wide range of operating conditions. Today 5 or 6 speed automatic transmissions are pretty much the minimum in New York, and 7 and 8 speeds are fairly common.
Obviously these sophisticated car transmissions are very expensive. In fact, next to your engine, your transmission is the most expensive component in your vehicle, so it pays to take good care of it. Modern transmissions can adversely affect car engine performance when they arenít working right.
All auto makers have a recommended service interval for changing your old, contaminated transmission fluid. Getting transmission service on schedule at Danís Auto Service in Taberg keeps it operating at its best and can prevent expensive damage. Ask your considerate Danís Auto Service tech if itís time for an automotive analysis of your transmission.
Todayís Rome car care article focuses on PCV valve replacement. The PCV valve is a little, inexpensive part that does a big job for your car. PCV stands for Positive Crankcase Ventilation.
The crankcase is the bottom area of the engine that holds the oil. When the car engineís running, fuel is burned to generate power. Most of the exhaust from combustion goes out through the exhaust system. But some exhaust blows by the pistons and goes into the lower engine, or crankcase.
These hot gases are about seventy percent unburned
can dilute and contaminate the oil, leading to damaging engine
oil sludge. It can also cause engine corrosion in your car. At
high speeds, the pressure can build up to the point that
gaskets and seals start to leak.
Rome car owners need to know that over time, the vented gases will gum up the PCV valve and it wonít work well. That can lead to all of the problems Iíve already described, oil leaks, excessive oil consumption and wasted gas.
Fortunately, itís very easy to test the PCV valve and quick and inexpensive to replace it at Danís Auto Service. Even so, itís often overlooked because many Rome drivers donít know about it.
Check your car ownerís manual or ask your Danís Auto Service advisor. If this is the first time youíve heard of a PCV valve, you might be in line for a PCV valve replacement.
Please ask us about your PCV valve. For the price of a couple of burger combo meals, you can avoid some very expensive deep engine repairs.
