are international maxxforce engines any good
Oso2, International tells me that you won't hurt your MaxxForce, which is an overhead cam engine, by revving it high, up to 2200 RPM while braking. Your exhaust type engine brake will work very well under load going down hill in position 3 if you do rev it high. Mine has never betrayed me. Since fuel economy is best at lower engine speeds, MaxxForce has a broad enough torque band to cruise at 1,300-1,400 rpm with more than a little in reserve for the hills. Peak torque sits between 1,000 and 1,200 rpm. The lack of engine noise made for a pleasant drive, too. MaxxForce uses two water-cooled air intercoolers in series after each turbocharger. There is no charge-air cooler on this engine. As a result, air intake air temps can be kept very close to ambient temperature, International says. That’s good for the fuel-to-air ratio, good for efficiency, and good for drivability. My first impressions of the MaxxForce engine are good. It may be new to North America, but it’s got a good track record in Europe. It’s light and torquey, and more than able to move typical linehaul or regional loads efficiently. If your operation doesn’t demand a big block engine, MaxxForce is worthy of consideration. Streets & Sanitation Trucks. Neither snow, nor potholes, nor recyclables, nor refuse will keep your from your appointed rounds. Not when you have the power and performance of an International® that, like you, people can count on day in and day out. To achieve good performance at low rpms, MaxxForce has combined dual-stage turbocharging with high injection pressures and optimized intake air temperatures. There are two turbos on the engine, operating in series, but independently of each other. Each are “simple” turbos, i.e., not variable geometry designs. Mine's rated at 475hp/1700lbs and it has plenty of power - not that I've ever driven a fire-breathing Cat, but for most purposes it's fine. One big plus in my books is that the engine is very quiet. On the flip side, my engine brake (which I believe is a Maxxforce exhaust brake) is pretty useless. Fire & Emergency Trucks. When seconds count, rely on the rich heritage of International’s range of topline emergency response vehicles to lead the way. With roomy cabs for extra crew and gear, our trucks are made to tackle your most demanding and unpredictable duties. Local Delivery Trucks. Your customers are counting on you. Their customers are counting on you. That’s why you count on International® Trucks. From fuel economy to maneuverability, durability to performance power, it’s more than a truck; it’s your partner. I suspect actually, that the problem is a cracked part in the exhaust. I even suggested that to International, but they'd rather replace the engine and not the exhaust pipes. I guess they have one last group of parts as suspect. Everything but the DPF, Oxygen sensor and Catalytic converter in the exhaust system.
Yes,international maxxforce engines any good.
