Page 66: Srs Airbag

The Volvo SRS Airbag provides increased protection in frontal collisions, where the vehicle collides with a ﬁxed or heavy object with enough force to activate the sensors which then activates the airbag.
Page 67: Srs System

Additional Safety Features SRS System The inﬂatable airbag is folded into the cen- ter of the steering wheel. It inﬂates in the event of a serious collision above a certain level, where the angle of impact, crash severity, speed and nature of the object in- volved in the collision all play a part in whether or not the airbag is activated.
Page 68
If a problem develops in the system, the INFO telltale will come on together with the SRS telltale. CAUTION The vehicle should be taken to an autho- rized Volvo Truck dealer immediately if the SRS telltale stays on or lights up when the vehicle is being driven.
Page 69
Additional Safety Features Warning Labels The label attached to the left hand sunvisor shows the year and month when a Volvo Truck dealer should be contacted for a speciﬁc inspection and for a possible re- placement of the airbag. This is done to guarantee the function of the airbag after the stated date.
Page 70
Additional Safety Features Any queries concerning the SRS system should be directed to a Volvo Truck dealer. There is no maintenance required for the SRS system until the date stated on the warning label located on the left hand sun- visor.
Page 71
If the airbag has de- ployed, the following is recommended: • Have the vehicle towed to a Volvo Truck dealer. Even if the vehicle can be driven after a collision, it is not recommended to drive the truck with the airbag deployed.

Use the recommended preventive maintenance (PM) program that Volvo Trucks North America, Inc. has developed for the vehicles. This ensures optimal en- ergy efﬁciency from all components that are important to fuel consumption.
Page 245
Fuel Economy Driving Axles An axle out of alignment will increase rolling resistance. Regularly check the front wheel alignment and axles on both the trac- tor and trailer/semi-trailer. If they are correct, there will be less rolling resistance, and therefore, lower fuel consumption. A good sign of an axle or wheel out of alignment is uneven tire wear.
Page 246
Fuel Economy Driving External Environment Under unfavorable conditions, the external environment can have a negative effect on fuel consumption. This can be broken down into two main groups: weather and wind, and the nature of the roads. Rain, snow, icy conditions and headwinds have a large neg- ative impact on fuel economy, as do hilly roads and uneven road surfaces.

General All Volvo vehicles are designed to meet or exceed all applicable federal brake stan- dards and regulations. They use a dual circuit, compressed air system. It consists of two independent brake systems that use a single set of brake controls.
Page 279
Brakes Both circuits are piped into a dual brake valve, which simultaneously applies front and rear axle service brakes during each brake application. In the event of a failure in either one of the circuits, the other cir- cuit becomes the emergency circuit for applying the brakes.
Page 280: Brake System Controls

Brakes Brake System Controls The air compressor, governor, pressure reg- ulator valve and reservoirs are control devices. Their function is to build up, maintain and control air pressure in the reservoirs. This is so that pressure is held constant between the minimum and maxi- mum range established for air brake operation.
Page 281
Brakes From the operator’s viewpoint, operating the foot brake valve of a vehicle equipped with air brakes differs very little from the operation of a conventionally braked vehi- cle. Because the operation of the brake pedal requires scarcely more effort than de- pressing the average throttle pedal, air brakes are naturally much easier to control.

Brakes Parking Brake/Trailer Supply Valves Trucks/Tractors have two air control valves on the instrument panel: • Trailer Supply (red octagonal knob) • System Park (yellow diamond knob) The two air control valves are intercon- nected and interacting. The System Park valve supplies and controls the Trailer Air Supply valve.
Page 284
Brakes Parking Brake Release VN models have engines equipped with en- gine electronic control units (EECU). These have two features that may impact the brake system. One is the anti-stall device in the EECU which senses torque demand and automatically controls the engine to com- pensate and maintain speed.
Page 285
Brakes There is also an engine shut-down device in the EECU that shuts down the engine af- ter a pre-programmed time in order to save fuel. This is activated when the yellow parking brake knob is pulled out. There- fore, some drivers park and release the parking brakes using only the red knob to keep the engine running.
Page 286
Brakes Spring Brake For Parking Never leave the vehicle without being certain the parking brakes are set or that other precautions are taken to prevent the vehicle from rolling. Failure to do so can result in serious personal injury or death. The parking brake mechanism uses spring pressure as a separate power medium to ap- ply the service brakes on the driving axles.

Volvo VNL, first generation

Tractors from the WIA and WCA series were discontinued and replaced with the first-generation VNL. Every model in the VN range is marketed as a truck tractor intended to haul heavy cargo over long distances. The effectiveness of the engines is a determining factor for such critical objectives. Powering the Volvo VNL tractor are VED 12 diesel engines of 12, 10, or 6 liters, producing 431, 390, or 349 horsepower via one of 14 manual gear ratios. It is possible to swap any engine or transmission made specifically for tractors into this model.

The VN line has a “day” small cab lengths of 104, 155, and 195.6 cm, in addition to longer cabs that may be used as living or sleeping spaces. The cab and living quarters are integrated, and it has a stronger structure, better suspension, and increased noise insulation to prevent major deformation in the event of a tractor rollover.

Volvo VNL, Generation 2

Exploring alternative energy sources is key to the company’s strategy for growth. While VNX has seen the majority of new releases, the VN series has seen several. Volvo Trucks plans to provide new engine options using alternative fuels shortly. Dimethyl ether is an energy-efficient fuel with little environmental effect, and the firm intends to use it in its vehicles.

Dimethyl ether is widely utilized now, although not as a fuel. Finally, DME may be made from renewable and nonrenewable sources (biomass). The conclusion follows years of research and development, field testing, and consultations with fuel producers and experts. The Volvo VNL DME series’s D13 engine is where DME technology first appears.

Volvo VNL 300

The D13-LNG series, which uses liquefied natural gas as fuel, debuted in 2013 at an exhibition in the American city of Louisville. The new engine outperforms conventional gas engines by 20% and outsavers diesel engines in terms of fuel efficiency. In addition to the diesel engine, Volvo has suggested a compressed gas-powered variant (CNG – compressed natural gas).

Compared to other vehicles in the VNL family, the VNL Hybrid is more fuel efficient and quicker, but its high price prevents it from being made available to drivers.

Volvo VNL 300

Equipment Volvo VNL Hybrid tractor

After its debut in 2010, Sweden’s Mean Green Hybrid high-speed tractor quickly became a global sensation after breaking the world speed record on June 9 of that year. This vehicle had a top speed of 166.7 kilometers per hour. A modified electric motor adding 200 horsepower was installed in the vehicle. Together with a 16-liter diesel engine producing 700 horsepower, it propels a tractor. In addition, there has been a reorganization of the gas distribution system. As a result, it was upgraded to 1,900 horsepower when everything was done.

A Volvo VNL Hybrid broke two world records on the runway at Wendover Airport in April of 2012. At a distance of one kilometer, the traveling speed was 236.57 km/h, whereas the starting speed was 153.25 km/h.

Volvo VNL tractors: specifications

All VNL models below 670 come standard with one of four engine options: the D11 (355-405 hp, 1550 – torque), the D13 (375-500 hp, torque – 2050), the D16 (up to 600 hp. at maximum torque – 2050 Nm), or the Cummins ISX15, which is not the salt of the earth due to its power (up to 550 hp), torque (1850 Nm), or fuel economy. Volvo VNL tractors with serial numbers higher than 670 D11 still need to install it.

The VNL 300 and 430 are designed for local transportation and trailer hauling. In contrast, the Volvo 780 is geared toward businesses that want a dependable vehicle capable of transporting huge goods. It’s a highway automobile built for long shifts.
