The Mercury Cars Guide : February 14th 2009
Saturday, February 14, 2009 Classifieds 62 300 400 • carsguide.com.au Isuzu not sold on hybrids While Hino is convinced of the merit of hybrids, archrival Isuzu has reservations aboutthem less fuel, but there are a lot of factors that have to fall into place for anoperator to achieve the best outcome from them. Fundamentally, they’re very dependent on the type of traffic they operate in, and the way they’re driven. Hybrids work best in high- density, stop-go traffic and when they’re driven for economy. They don’t work so well in free-flowing traffic or when driven by some- one who makes use of the extra performance thatcomeswhenthe diesel engine and electric motor are working in tandem. To get an accurate measure of T their environmental impact and fuel savings in the Australian environment, Isuzu has com- menced a test program using one of the latest N Series hybrids its parent is producing for the Japa- nese market. Isuzu’s hybrid test truck is based on the new 700P N Series and is now in production in Japan. In Tokyo, with its clogged streets and slow moving traffic the hybrid works well, but in the minds of the local Isuzu people, Australia’s traffic may not be as hybrid-friendly. Hence the test, which is being run in Melbourne in tandem with a couple of similar Isuzu diesel trucks and another truck from a rival company. To date the results are promis- ing, but at the same time they are confirming Isuzu’s belief that the application and driving style are critical to the outcome. The tests so far show that the reduction in greenhouse gases and fuel consumption range from a low of eight per cent to as much as 22 per cent. The higher results come from applications in which the truck is working in high-density traffic and regularly coming to a halt at traffic lights or in clogged streets. The lower savings are when it is on the move more and rarely stopping. It also helps enormously if the driver drives for economy using the hybrid system to advantage.

The6500kgGVMHybridontest is the equivalent of an NPR in Isuzu’s local jargon. Whereas a regular NPR would have Isuzu’s 5.2-litre, turbo diesel engine, the hybrid’s engine is a 4JJ1-TCS 3-litre, turbo diesel rated at 150 horsepower at 2800rpm. EGR is used to clean up the NOx emissions and a diesel par- ticulate filter takes care of the particulates before they escape into the atmosphere. It’s yet to be tested for compli- ance to our ADR 80/02 emission limits, but it does comply with the Japanese New Long Term limits, which means it will be compat- ible with the Australian rules once testing has been completed. In addition to the diesel engine, the Hybrid is helped along by a synchronous electric motor that produces 25kW at 1100rpm and 274Nm from zero to about 1000rpm. The electric motor is connected to the driveline through the power take-off on the transmis- sion and assists the diesel under acceleration, which is why driv- ing style is so critical to the savings achieved by the hybrid. Accelerate modestly and the savings will be substantial, but accelerate hard and the savings will be much less. At constant speed the truck is propelled by the diesel engine alone. Under deceleration or braking the electric motor is used to recharge the low mass 346-volt liquid cooled Lithium-Ion battery pack, one of the major innova- tions on the new 700P-based mod- el, and assist with the braking. In addition to the savings achieved by having the electric motor assist the diesel under acceleration, the other source of fuel and emission reductions is the idle-stop function. Whenthe truck comes to a halt, providing the driver holds the brake, the engine will stop, saving the fuel it would consume while idling and slashing the tailpipe emissions. As soon as the driver’s foot is lifted off the brake pedal the electric motor comes to life and acts as a starter to restart the engine and allow the truck to be driven away. Although it sounds clumsy, it happens quite quickly and there’s only a slight delay in getting going. While minimal the delay was felt to be greater than that experienced in Hinos 300 Series Hybrid when Big Wheels drove it last year. Also, the Isuzu system doesn’t comeinto play if the turn signal is operating. That’s for safety, given that a driver wouldn’t want the engine to cut out while sitting waiting to turn right in the middle once the traffic clears. However, it does have the effect of reducing the fuel and emission savings. Isuzu’s hybrid differs from the Hino in that it has a six-speed AMT automated shift box, which is claimed to further add to the savings of the Hybrid. On the day Big Wheels put it through its paces in the Mel- bourne CBD it had 660kg of concrete in the rear to give it a workout. Operating in medium-density traffic—peak hour had passed— the Isuzu Hybrid comfortably kept pace with the traffic, although a delivery driver in a hurry to get to their next drop-off would likely drive it harder. However, using the diesel and electric motors to their advan- tage, could result in a loss of hybrid savings. The AMT was smooth in shift- ing, although the shifts could be swifter so there’s less of a sinking feeling between gears. In addition the time taken to restart the engine could be re- duced, it required a little too much time to get the fire going again and drivers would be tempted to turn the system off. Ultimately, the problem for Isuzu, and indeed anyone trying to sell a hybrid, is their cost. They are substantially more expensive than a regular diesel, which makes it difficult for an operator to justify. It’s really only the big fleets that feel a corporate responsibil- ity to be clean and green and could justify buying hybrids. They are simply not viable for the little guys. For that reason alone Isuzu is being very cautious about com- mitting to a hybrid future. While the company wouldn’t comment on its plans for hybrids, simply preferring to say that hybrids are but one alternative it has under consideration for fu- ture introduction, it is more openly enthusiastic about intro- ducing CNG-powered trucks. So enthusiastic is Isuzu about CNG that it will have at least two models on show at the Brisbane Truck and Machinery Show in May, and very likely it will have three models on sale here later this year.
