TBI. MPI. It all sounds so impressive, but all it means is how you go about squirt- ing gasoline into your engine so you can go for a drive. Almost all engines are fuel.injected now (EFI—electronic fuel injection). Some are injected at a single point in the intake manifold (TBI—throt- tle body injection), while some have more injectors to get the fuel distribution among the cylinders as, even as possible (MPI—multi-point injection). Each fuel injector opens and closes to squirt fuel into the engine thousands of times per second. It's all controlled by the engine's com- puter, which is why the engine management system is so important to how well your car runs. Today's computers are so smart that they can monitor the ignition timing, exhaust temperature and oxygen content, engine load and make adjustments as needed to keep the car running at its most fuel effi- cient. High fuel efficiency also translates into low exhaust emission. Typically, fuel injectors for a multiLpoint system are located along a rail to position them for, optimum fuel. distribution. Because there are several, each one only injects a little fuel—so the outet hole is 'tiny. This hole can get clogged, causing rough idle.and inefficient driving. Usually, this happens if you make a lot of short trips or leave your car idling. Sometimes, you can clean the injectors out by taking the car out on the highway and driving at high- way speeds for 30 kilometres or so. ' All the major gasoline marketers sell gasoline that has detergents and injector cleaners added to keep fuel -injected cars operating cleanly and efficiently. However, if you take a lot of short trips, it's a good idea to help 'these cleaners along by adding some fuel system cleaners, available at all automotive stores. These products will keep the injec- tors and valves clean, eliminating stalling and hesitation, rough idling ar+d engine knock. Car Care Canada Pumping Your ABS (CCC)—No, we're not talking about a new device for firming your waistline. We're talking about Anti-lock Braking Systems (ABS), which have been oalled the greatest safety innovation since the seatbelt. There are more and more cars on the market with ABS as an option or even as a standard feature. But there arc many who don't under- stand how the system works or what it can and cannot do for a driver in bad weather. 'Here's a quick quiz from Car ' Care Canada to see if you under- stand ABS: 1. Even with ABS, on a slippery road I should pump the brakes for maximum stopping power. Truc or False. 2. The main advantage of ABS is that it allows me to retain steer- ing control while applying maxi- mum braking. True or False. 3. When I press down on the pedal on a slippery day, I feel the pedal press back against my foot , and I hear a humming noise. This mean the brakes are failing. True or False. 4. The ABS warning light comes on. This means I hate a total brake failure and I must not drive the car. True or False. Answers 1. False. The ABS system will pump,only the brake or brakes on wheels that are slipping. The other brakes remain fully applied, so you'll stop faster. The ABS system can pump the brakes that need to be pumped many times a second. 2. True. Because your wheels never lock up, you retain steering control. This gives you the option of steering around an obstruction or stopping before you hit it. 3. False. This is normal and tells you that'the ABS system is work- ing. Use a firm steady pressure on the brake pedal. 4. False. The ABS warning light . means an ABS system problem— your brakes will work normally, unless the brake warning light is also on. However, you no longer have ABS, so get that system checked as soon as possible. Car Care Canada ' • There's only one Jeep®. And there's only one Jeep. sale..

Avoid the expense and inconvenience of a breakdown on the road far from home. By spending a few extra dollars for complete cooling service on your car, truck or van before your summer holiday, you could save big dollars in the long run! Car Care, Canada recommends the following ways to save money and to take care of your vehicle's cooling system: 1. Save labour charges (or your own time, if you do your own work) by taking care of all necessary replacements at one time. When one hose or drive belt needs replacing, you are likely to find more in marginal condi- tion. Rubber components under the hood live in a hostile environment, surviving tempera- tures ranging from sub -zero to more than 118 degrees Celsius, circulating up to 28,000 litres of coolant per hour at up to 7.2 kg of pressure. They warrant periodic attention. Have the system pressure tested and inspect all hoses, clamps and connections. 1 -loses may become spongy and soft, or in some cases, brit- tle. Also, belts should be inspected for signs of cracked, frayed or glazed conditions: You may not know that the radiator cap serves as the safety valve in your cooling sys- tem. The pressure test, available at most serv- ice dealers, will not only disclose existing or potential leaks in the system, it also will detect a faulty pressure cap. 2. Save gas with a new thermostat. An engine, like your body, has an optimum operating temperature. Most engines run in the 97-113 degrees Celsius range, controlled by the cooling system thermostat. But fuel econ- omy will drop as much as 10% — 20% when engine operating temperature falls below 53 degrees Celsius. The small investment to replace a faulty thermostat can soon pay for. itself, not only in gas savings, but also in terms of reduced engine wear. 3. Avoid premature engine overhaul through timely maintenance. Thccost of repairing an engine damaged by overheating (or by operating too cold. in the winter) can run into thousands of dollars, an expense that can be avoided with thorough and proper servicing of the cooling system. In addition to the above-mentioned inspec- tion, complete cooling system service should include flushing of the system and installation of fresh antifreeze coolant (in a 50-50 mixture with water).
