Deceleration artifact: ISM + JACBOS = special brake engine
Introduce the working principle of the JACBOS brake system from a scientific point of view. The JACBOS brake system uses a compression energy release device to convert the output power of the engine into an air compressor that can absorb power several times better than similar products. Braking performance.
Xi'an Cummins ISM 11-liter engine braking system
When braking is required, the exhaust valve is opened by the brake system when the piston goes up to the end during the compression stroke in which the engine is doing negative work, and the high-pressure gas is released. This is the stroke of the engine in the only expansion stroke that does positive work. Negative pressure sucks up the piston, doing negative work to absorb vehicle kinetic energy and reduce vehicle speed.
working principle
Faced with these boring principles, isn't it really clear to everyone what the use of this guy really is and what benefits does it bring to the car? So let's take a look at what kind of effect it has brought on a vehicle.
Higher security
Downhill is easier to control:
As the saying goes, it's easy to go down the hill, it's easy for a truck to go uphill, it's easy to go downhill, and the truck's weight makes it difficult to control the downhill speed. The high load using the engine brake can reasonably control the speed of the vehicle so that the vehicle can reach the bottom quickly and safely. We exemplify a total weight of 40 tons and a 6% gradient. Ordinary vehicles can only travel at 2 speeds and 9 KM/h. A car with a compact Cummins engine with a JACBOS braking system can run at 7 speeds of 51 KM/h. And more secure.
6% ramp test
Shorter braking distance:
A second may be a particularly short time, but a high-speed vehicle can fly for tens of meters in one second. When the brake occurs, the JACBOS engine brake responds instantaneously, effectively shortening the brake response time by about 1 second. When the truck is driving at a speed of 90 kilometers per hour, the braking distance can be shortened up to 25 meters. ·
Avoid brake pads and hub temperatures that are too high due to continuous wheel braking:
The fear of long-distance transportation is that the wheel brake temperature is too high. After the wheel brakes are continuously used for 3-5 minutes, the temperature of the brake pads rises sharply, the wear is aggravated, the braking effect drops sharply, and even the brakes fail, causing serious safety problems. . The use of engine brakes can reduce the need for 85% of wheel brakes, thus effectively avoiding traffic accidents caused by brake failure. The same reasoning leads to a sudden increase in hub temperature due to continuous braking, which causes the tire temperature to rise further rapidly on the basis of the temperature increase caused by the friction between the tire itself and the road surface, thereby increasing the risk of bursting and using engine brakes. Reduce 85% of wheel brakes, effectively reducing the chance of a blowout.
Better economy
Saving 500 liters per year:
If you have a chance to save 500 liters of oil every year, what would you choose? When the Cummins engine brake system is turned on, the engine stops spraying, and the fuel efficiency is about 1%. (According to the annual operation of 120,000 kilometers, fuel consumption is 38-40 liters per 100 kilometers, saving 1% fuel, saving about 450-500 liters of fuel each year.) Every cent of the trucker is hard-won, saving unnecessary Consumption is worth every sweat for the user.
Save time and improve productivity:
For truckers, every shipment is race against time. Cummins Engine Braking System can achieve a braking power of 326 horsepower, which effectively shortens the braking distance. This allows the driver to run at a reasonably fast speed on the road and on the slope. Safety goes downhill with reasonable speed.
Reduce maintenance costs:
Brake pads exchanged too hard, each foot brakes are distressed? Using Cummins engine brakes can reduce 85% of the wheel brakes, significantly reduce the frequency of brake pads, extend brake system life, reduce 2-3 times per year Replacement of the brake pads; while drastically reducing the temperature rise of the hub due to continuous braking, slow down the tire due to high temperature aging and rapid wear, which can extend the tire life of about 25%.
Increase load:
In order to reduce the temperature of brake discs, common vehicles must be equipped with a shower tank (mostly weighing about 1 ton). The Cummins engine has a braking power of 326 horsepower and only weighs more than 20 kilograms. It can replace the shower tank in most cases to ensure safety. Under the circumstances, it can effectively reduce 1 ton and realize 1 ton of multi-pull goods.
