Chrysler flathead engine
The Chrysler flathead engine is a flathead inline automotive engine manufactured by the Chrysler Corporation from 1924 through the early 1960s. It came in four-,six-, and eight-cylinder configurations and varying displacements, with both cast iron and cast aluminum cylinder heads. It was installed in Chrysler, DeSoto, Dodge, and Plymouth branded vehicles.
Chrysler introduced a straight-four in 1926 when the Maxwell Motor Corporation was re-organised into the Chrysler Corporation in 1925. Initially used by Chrysler, the straight-four was fitted to Plymouth cars and Dodge light trucks beginning in 1929, lasting in production through 1933.
The original version displaced 185.8 cu in (3,044 cc) and produced 38 hp (28 kW). This was only produced in 1926, with displacement reduced to 170.3 cu in (2,791 cc) for 1927 and 1928. Power was initially rated the same but was upped to 45 hp (34 kW) during the 1928 model year.
After the introduction of the Plymouth brand in 1929, the base engine was subjected to a major redesign and enlarged to 175.4 cu in (2,874.3 cc) with the power rating remaining the same. It was also used in Dodge light trucks in 1929–1930. The engine was enlarged again to 196.1 cu in (3,213 cc) in 1930 with 48 hp (36 kW), for 1931 with 56 hp (42 kW), and 1932 with 65 hp (48 kW) for Plymouth only; Dodge continued with the 48 hp (36 kW) from 1931 to 1933. A small-bore version was developed for export markets in 1931, with a narrower bore which brought the RAC rating down from 21 to 15.6 hp. For 1932 the bore was reduced further, bringing the tax horsepower rating to just beneath 15.5.
Chrysler did not offer a four-cylinder engine again until 1981 with the Chrysler 2.2 & 2.5 engine used in the Chrysler K platform.
The first straight-6 was the B-Model (seven main bearings) and introduced in 1924 with the first Chrysler Corporation production, the B70. An upscale version designated E-Model equipped the new Chrysler Imperial E80 in 1926, and a downscale one named H-Model followed in 1927 (Chrysler Series 70). After the purchase of Dodge Brothers Company in 1928, Chrysler Corporation had five straight-6s in production with the addition of the Victory and Senior Dodge Brothers engines.
So, with the introduction of the new Desoto brand in 1929, came a new and cheaper to produce six cylinder, the K-Model, with four main bearings and deep skirts. By mid-1930, it partially replaced the previous engines in varying displacements on passenger cars, in conjunction with an all-new straight-8 engine. Only the Imperial's engine remained in production for the Dodge Trucks' 2-ton Models F-40 & K-50, 3-ton models F-60 & K-70, 2 & 3-ton Special, buses from 1930 to 1934-35. To replace these two engines, a new and very large six cylinder was launched in late 1936 (331 cu. in.), which grew to 413 cu in and was las used in the C-3 Series[clarification needed] in 1956.
In 1932, the Ford flathead V8's launch shook up the market, expanding the demand for larger engines to even entry-level brands. A new straight-6 for Plymouth (PC/PD) and Dodge (DP/DQ) came in production in 1933, known as the "23 in block", featuring a shallow skirt and a head desk length of 580 mm,[clarify] followed by a larger ("25 in block" – 640 mm) variant for Desoto (S3) and Chrysler Royal (C16) in 1937, marking the K-Model end everywhere but in Canada. When Chrysler established an engine foundry in Windsor, Canada, in 1938, it was decided to only use the long block for all Canadian-built engines. These engines received a trailing "C" in their designation. Thanks to judicious bore and stroke dimensioning, the Canadian 201- and 218-cubic inch engines had nearly identical displacement to their American cousins.
