Title: Constant horsepower internal combustion engines
IPC: F02B37/00
Filed: 1969-03-04
Abstract: 1,222,304. Regulating I.C. engines, turbochargers. MACK TRUCKS Inc. March 4, 1969 [March 9, 1968], No.11540/69. Headings F1B and F1G. In a turbocharged multi-cylinder engine the fuel supply is regulated by operator-controlled means and by engine-speed controlled means which regulate the maximum fuel charge supplied to the cylinders per stroke to increase as the engine speed decreases throughout a range of useful operating speeds and decreases the fuel supply in an idling speed range below the useful operating speed range. The turbocharger comprises a blower driven by a turbine having separate gas passages connected to a number of exhaust manifolds for separately conducting and directing the exhaust gases against the rotor vanes, the fuel and air supply being controlled so that a negative scavenging pressure is produced in the cylinders in the upper end of the range of useful operating speeds and an increasing positive scavenging pressure is produced as the speed decreases towards the lower end of the range of useful operating speeds to match the increasing fuel charge per stroke and thereby provide a substantially uniform horsepower output. The separate exhaust manifolds (17, 18), Fig.2 (not shown) receive exhaust gas from the front three and rear three engine cylinders respectively and the exhaust gas is directed to the turbine volute casing which is divided by a partition (26), Fig.3 (not shown). The pistons (12), Fig.5 (not shown) are cooled by an oil jet directed against their undersides. The fuel control governor system comprises a fulcrum lever 33, Fig.4 connected by a link 34 to a rack 35 which controls the amount of fuel injected. The lever 33, is lowered and turned clockwise about its lower end by an accelerator pedal to increase speed and moved by an engine speed governor to engage a cam nose 43 against slope 40 of cam 32 from 2100 r.p.m. down to 1200 r.p.m. At 1200 r.p.m. screw 44 engages surface 42 due to the governor action tending to turn lever 33 counter-clockwise and move the cam nose away from the plate and into the off or idling position. Between 2100 r.p.m. and 1400 r.p.m. the nose 43 engages slope 40 and between 1400 r.p.m. and 1200 r.p.m. the nose 43 engages slope 39 so that the fuel supply is increased with falling speed until the screw 44 engages surface 42.
