The WDM-3C were just upgraded and more powerful WDM-3As with the ALCO engine gain rebuilt to output 3300 hp. It was the first follow-up experiment after the WDM-3A to squeeze more power out of the ALCO engine, an intermediary that would later lead to the development of the WDM-3D.
The Indian locomotive class WDM-3 was a type of diesel-hydraulic locomotive that was developed by Henschel for Indian Railways in 1962. The model name "WDM-3" stood for broad gauge (W), Diesel (D), Mixed traffic (M) engine, 3rd generation (3). These locomotives were put into service between 1970 and 1971, and a total of eight were built between ...
The engine is classified WDM-3D though it outputs only 3300 hp and not 3400 hp as the name should suggest. They entered service in 2003. A total of 590+ WDM-3D were built at Banaras Locomotive Works (BLW), Varanasi between 2003 and 2016. The WDM-3D is one of the most successful locomotives of Indian Railways serving both passenger and freight ...
They entered service on 18 July 1995. A total of 1,164 WDG-3A units were built between 1994 and 2015 at BLW, Varanasi with a few units being produced by Diesel Loco Modernisation Works (DLMW) and Parel Workshop. It is the dedicated freight version of the highly successful WDM-2 and shares the same engine and horsepower rating with WDM-3A.
Typical airflow in a four-stroke engine: In stroke #1, the pistons suck in (aspirate) air to the combustion chamber through the opened inlet valve.. A naturally aspirated engine, also known as a normally aspirated engine, and abbreviated to N/A or NA, is an internal combustion engine in which air intake depends solely on atmospheric pressure and does not have forced induction through a ...
The M4+2 engine, also known as the double-piston internal combustion engine, is a type of internal combustion engine invented by Polish patent holder Piotr Mężyk. [1] The M4+2 engine took its name from a combination of two-stroke engines and four-stroke engines. The two-stroke combustion engine is characterized by a simple construction and ...
GE 7FDL-12, 12-cylinder engine used in locomotives, such as the GE P32AC-DM [2] GE 7FDL-16, 16-cylinder engine used in locomotives, such as the GE AC4400CW [3] GEVO series (bore 250mm, stroke 320mm [4]) GE GEVO-6, 6-cylinder engine used in locomotive repower/modernization applications [5]
[1] 44 units produced until February 2001 (Indian Railway road number 15501-15544) had dual cab forward design different from other classes of locos built by DLW (WDM-2, WDM-3A, WDG-3A and WDP-1). [2] These new locomotives have control stand similar to many electric locomotives. They are the re-geared versions of the WDM-3A. This was IR's ...
