6LPA-DTP | 6LPA-STPYanmar | Marine & Industrial, Marine Diesel Engines
6LPA-DTP – 191kW(260hp)
6LPA-STP – 232kW(315hp)
Light in weight, small in size, high power outputs.
Cam Area Improvements: These engines contain many high performance features sure to appeal to the serious motorboater.
The overhead cam design develops max hp at higher revs, allowing smaller, smoother running propellers. Camshaft is belt driven, reducing weight, numbers of parts, gear wear and noise. The STP model even features 4 valves per cylinder for enhanced breathing and top end performance.
Better Fuel and Air Management: A waste-gated water-cooled turbo really makes things happen when the throttle is put down hard. To reduce embarrassing black smoke at these times, the 6LPA series engines have boost-compensated distributor-type fuel pumps. And burn efficiency has been improved as well.
Reduced Vibration and Noise: Two stage springs in fuel injectors reduce injection noise. Ladder-frame, full block-width crankshaft bearing cap structure reduces lower block area distortion and fights bearing slap. And of course belt drive makes for big cuts in timing gear noise, while the 12 balance-weight crankshaft and rubber engine mounts soak up much of the usual diesel vibration.
Extras: Ordering the STP gets you a “go fast package” of bigger oil cooler, gallery cooled pistons and big breathing 4-valve head.
Engines can be ordered with optional instrument panels B, C, or D. Panel B mounts the usual tachometer and vital sensors for battery, temperature and oil, but in addition has sensors for
i) fuel/water separator water level,
ii) seawater flow at intercooler, and
iii) waste-gate valve blockage (boost pressure),
Panel C and D offer more sensors again, namely for
iv) heat exchanger fresh water level.
The aim is to go faster on less fuel, while at the same time keeping a far better eye on all those vital engine health functions.
