A 500-HOUR endurance test of a IA Leyland 9.8-litre oil engine was recently carried out under the supervision of inspectors from the Ministry of Supply. The performance graphs showed that the b.h.p., torque and fuel consumption improved progressively and were reaching their peak towards the end of the test.
The 500 hours were completed in 16-hour non-stop cycles, each cycle, with the exception of the last one, consisting of four hours at 1,800 r.p.m. developing 105 b.h.p. (rated load); four hours developing 52.2 b.h.p. (half load); an hour with an output of 117 b.h.p. (10 per cent. overload); 3+ hours producing 105 b.h.p. (rated load), and 3+ hours developing 52.5 b.h.p. (half load).
The 16th period was similar except that after the first eight hours the engine was run at no load for 30 minutes to check the efficiency of the injection system.
At the end of the test the engine was producing 125 b.h.p. at 1,800 r.p.m. at the 10 per cent, overload rating. The torque at 1,100 r.p.m. was 412 lb.-ft., and fuel consumption at the same speed fell to 0,34 pt. per b.h.p.-hr.
Detailed examination of the stripped engine showed that the general condition was such that it could be rebuilt with every confidence that it would be equal to a new unit.
ORGANIZER HAD FREE SEATS: NO BREACH OF LAW
!ARROW magistrates decided recently J that although a private-party organizer had been given the equivalent of two free seats and had been reimbursed by the hirer for empty seats, no breach of the contract-carriage law had been committed.
Mrs. Violet Neil, of Jarrow, was summoned for causing vehicles of Hall Bros. (South Shields), Ltd., and Alexander Todd, Ltd., South Shields, to be used as express carriages without road service licences. The companies were also prosecuted. The charges arose from trips to London last summer organized by Mrs. Neil on behalf of various organizations.
The magistrates dismissed the charges. The prosecution asked for a case to be stated.
