AHITHERTO unannounced version of the A.E.C. AV410 six-cylindered diesel engine is being fitted by Dodge Brothers (Britain), Ltd., Kew, in their 9-ton range of goods chassis. The principal difference between this revised A.E.C. unit and previous versions is that a C.A.V. DPA distributor-type fuel-injection pump is employed: this change affects also AV410 and AV470 engines installed by A.E.C.. Ltd., in their own chassis, although horizontal versions of these engines retain an in-line pump.
The DPA-equipped AV410, as used in the Dodge 9-tonner," is rated to develop 113 b.h.p, (net) at 2,200 r.p.m. and 300 lb.-ft. torque at 1,100 r.p.m. These figures indicate that the change of pump has slightly altered the power characteristics of this unit, the original ratings for which were 98 b.h,p. at 2,000 r.p.m. and 282 lb.-ft. torque at 1,300 r.p.m. The increased torque output, which occurs at a lower engine speed, should effect a noticeable improvement in road performance.
Dodge 9-ton chassis, which are available with wheelbases of 9 ft. 8;`, in., 13 ft. 7 in., or 17 ft. 9 in., were introduced a year ago. They have five-speed gearboxes and two-speed rear axles as standard, with air-hydraulic braking on all models. The gross weight rating is 14 tons, and as originally introduced the Leyland 0.375 110-h.h.p. engine was standard: the A.E.C. unit supplants this.
