New engine based on D6
The D6-435 is a newly developed model based on the D6 that was launched in 2003. Externally, it is an in-line six-cylinder diesel with a new turbocharger and a modified intercooler. Internally, it features a new cylinder head in which the valves have been relocated to increase airflow. The pistons are new, with matching combustion chambers. The intercooler, air intake and injector are larger. The cooling system has also been upgraded to cope with the higher output. Combined with state-of-the-art electronic common rail fuel injection and combustion technology, these features result in world-class performance. One of the design objectives was to provide lively acceleration without producing fumes. Torque already reaches an impressive 993 Nm at 2,000 rpm.
EVC as standard
Both the engine and the controls and instrumentation are integrated via Volvo Penta’s EVC (Electronic Vessel Control) system. This permits simple installation and gives high operational reliability. The CAN bus technology uses a serial data cable to replace conventional cabling for instruments and controls. Electronic controls for shift and throttle are standard.
Invisible technology produces visible environmental gains
During 2006-2007, both the US and Europe are introducing emissions requirements for diesel engines in leisure craft. The D6-435, together with all the models in Volvo Penta’s diesel range, meets the rigorous emissions requirements.
“It is mainly the electronic systems that enable engine combustion to be precisely controlled and fully monitored. Together with highly effective intercooling, high-pressure fuel injection and four-valve technology, this results in an engine that emits hardly any visible fumes or odors,” says Bertil Andersson, head of technical development at Volvo Penta.
Several transmission alternatives: straight shaft and down angle gearbox
The D6-435 is available with several reverse gear options, with a straight shaft and also a down angle gearbox, all with electronically controlled gear-shift integrated with the engines via the EVC system. As an optional extra, a low-speed function is available that uses a transmission with a slip clutch to enable the boat to be driven at about half the idling speed, which is useful when maneuvering in a harbor for example.
