The inline six-cylinder 71 series engine was introduced as the initial flagship product of the Detroit Diesel Engine Division of General Motors in 1938.. This engine was in high demand during WWII, necessitating a dramatic increase in output: about 57,000 6-71s were used on American landing craft, including 19,000 on LCVPs, about 8,000 on LCM Mk 3, and about 9,000 in quads on LCIs; and 39,000 ...
The 6-71 is an inline six cylinder diesel engine. [1] The 71 refers to the displacement in cubic inches of each cylinder. [1] The firing order of the engine is 1-5-3-6-2-4. [1] The engine's compression ratio is 18.7:1 with a 4.250 inch bore and a 5.00 inch stroke. [1]
The Series 92 engines were introduced in 1974. [8] Compared to the Series 71 engines they were derived from, the Series 92 featured a larger bore of 4.84025 ± 0.00125 in (122.942 ± 0.032 mm) and an identical stroke of 5 in (130 mm) for a nominal displacement per cylinder of 92 cu in (1,510 cc), from which the Series 92 derives its name.
Tachycardia, also called tachyarrhythmia, is a heart rate that exceeds the normal resting rate. [1] In general, a resting heart rate over 100 beats per minute is accepted as tachycardia in adults. [1] Heart rates above the resting rate may be normal (such as with exercise) or abnormal (such as with electrical problems within the heart).
Over a period of time, Detroit Diesel continued to further evolve the design of the engine. They finally brought the engine up to 137.5 hp (102.5 kW) per cylinder and 406 lb⋅ft (550 N⋅m) torque per cylinder; needless to say, this is a considerable amount of power coming from 149 cu in (2.4 L) per cylinder.
Detroit Diesel prescribed overhaul intervals of 500,000 miles (800,000 km), then raised that to 750,000 miles (1,210,000 km) after more experience was gained with the new engine. [ 3 ] In 1993, the 11.1 L (677 cu in) version was rated at 350 bhp (261 kW) (but would produce 15 more if the cruise control was engaged).
It consists of a brief speed-up in heart rate, followed by a slow decrease back to the baseline rate. PVCs can occur naturally in most otherwise-healthy adults, so measuring the characteristics of a given person's HRT can offer a non-invasive way to evaluate certain aspects of their cardiac or autonomic function without applying artificial ...
A medical monitoring device displaying a normal human heart rate. Heart rate is the frequency of the heartbeat measured by the number of contractions of the heart per minute (beats per minute, or bpm). The heart rate varies according to the body's physical needs, including the need to absorb oxygen and excrete carbon dioxide.
