ESP: Driving safely

Small commercial vehicles drive more safely with ESP. The Electronic Stability Program (ESP) from Bosch can prevent skidding effectively even before it begins. ESP intervenes at lightning speed when needed. Its sensor system detects the impending danger faster than any human being and issues instructions to the brakes and engine management. ESP can generate the precise brake pressure required on all four wheels and thereby keep the vehicle on track more safely. Especially for small commercial vehicles, this represents a substantial increase in driving safety.

Common Rail System: strong and economical

To master long ascents energetically, commercial vehicles need enormous traction capacity. This is where accumulator injection with the Common Rail System (CRS) from Bosch brings its full potential into play. CRS injects the diesel into the cylinders with a pressure of 1800 bar. The injection sequence can be designed as needed. The electronic control unit adjusts the injection process to changed driving situations in fractions of a second. Fuel energy is therefore used with exceptional efficiency.

But the Common Rail System not only improves engine performance. Fleet operators value the low fuel consumption and economy of CRS engines. And the environment benefits too: efficient fuel combustion ensures a substantial reduction in emissions.

LI-E alternator: economic and energetic

Commercial vehicle drivers have many electronic helpers on board who ease their work behind the steering wheel, such as radio and telephone, navigation systems, air conditioning and many more. In the engine compartment, electronic components like the engine management system carry out indispensable tasks. And all these systems have to be supplied with power reliably at all times.

That is where the LI-E alternators from Bosch come in. Compared to earlier models their efficiency has now been raised by another 7% to 74%. Nonetheless, they are also exceptionally compact and light. Consequently, they save up to 0.5 liters of fuel per 100 km.

Intelligent control electronics thereby monitor and direct the power requirements of all electrical devices and the battery’s state of charge.

The LI-E series comprises four alternator sizes with a rated current of up to 200 A in 14 V and up to 130 A in 28 V on board networks.

HEF starter: long-lasting and powerful
Long distances and high loads need strong engines with a large stroke volume. This is why diesel engines with up to 16 l piston displacement – a multiple of the value in average passenger cars – are generally used in commercial vehicles. Very efficient starters with high torque are needed for these large-volume engines to start reliably in all conditions.

They are provided by the HEF series from Bosch. HEF starters were developed specifically for the tough everyday work of commercial vehicles. They generate a very high starting crank for safe engine starting in every environment. With their two-step pinion advance concept, HEF starters make starting smooth and safe. At the same time, they are significantly smaller and lighter than conventional models, due to their advanced construction.

A unique feature of HEF starters is the interface for electronic triggering. It allows the vehicle electronics to prevent overcharging of the starter and the damage thereby caused. This feature and their robust construction mean that HEF starters reach a service life of 800,000 km

DENOXTRONIC: clean and economic

Commercial vehicles travel several hundred thousand kilometres in a very short space of time. This is why cutting emissions in commercial vehicles is especially important to protect the environment. But conventional catalytic converters and particle filters cannot cope with such heavy permanent operation.

This is why new SCR technology (Selective Catalytic Reduction) with the DENOXTRONIC from Bosch is employed to make sure trucks, too, are clean on the road. The SCR system consists of a catalytic converter which converts nitrous oxide and particles into harmless substances with the aid of the reduction agent AdBlue. To achieve maximum system performance, the AdBlue must be dosed precisely at every point in the operating cycle. This task is performed by the DENOXTRONIC from Bosch. It permits SCR systems to cut nitrous oxide emissions by up to 90% and particle emissions by up to 40%. At the same time, the engine can be laid out to save up to 5% fuel. This way, the system pays for itself very fast.
