Govind Ballabh Pant University of Agriculture and Technology, Pantnagar

After independence, development of the rural sector was considered the primary concern of the Government of India. In 1949, with the appointment of the Radhakrishnan University Education Commission, imparting of agricultural education through the setting up of rural universities became the focal point. Later, in 1954 an Indo-American team led by Dr. K.R. Damle, the Vice-President of ICAR, was constituted that arrived at the idea of establishing a Rural University on the land-grant pattern of USA. As a consequence a contract between the Government of India, the Technical Cooperation Mission and some land-grant universities of USA, was signed to promote agricultural education in the country. The US universities included the universities of Tennessee, the Ohio State University, the Kansas State University, The University of Illinois, the Pennsylvania State University and the University of Missouri. The task of assisting Uttar Pradesh in establishing an agricultural university was assigned to the University of Illinois which signed a contract in 1959 to establish an agricultural University in the State. Dean, H.W. Hannah, of the University of Illinois prepared a blueprint for a Rural University to be set up at the Tarai State Farm in the district Nainital, UP. In the initial stage the University of Illinois also offered the services of its scientists and teachers. Thus, in 1960, the first agricultural university of India, UP Agricultural University, came into being by an Act of legislation, UP Act XI-V of 1958. The Act was later amended under UP Universities Re-enactment and Amendment Act 1972 and the University was rechristened as Govind Ballabh Pant University of Agriculture and Technology keeping in view the contributions of Pt. Govind Ballabh Pant, the then Chief Minister of UP. The University was dedicated to the Nation by the first Prime Minister of India Pt Jawaharlal Nehru on 17 November 1960. The G.B. Pant University is a symbol of successful partnership between India and the United States. The establishment of this university brought about a revolution in agricultural education, research and extension. It paved the way for setting up of 31 other agricultural universities in the country.

    Modification of a CI engine into SI mode and its performance evaluation on biogas
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2007-07) Nagaraja, G.; Bhattacharya, T.K.
    In agriculture sector biogas is used in low horse power CI engines in dual fuel mode where about 30 percent diesel and 70 percent biogas are burnt in an engine to develop power. However, biogas has octane rating of 130 which is greater than the petrol (96) and therefore, there lies a potential to run such engines on 100 percent biogas by converting these engine into gas engines operating in SI mode. A constant speed, low bhp (7.4 kW), single cylinder, four stroke, direct injection, Kirlosker make engine having compression ratio of 16.5:1 was converted into SI mode. Major modifications include the removal of diesel fuel supply system, reduction of compression ratio (13:1), installation of spark plug, mounting of ignition system and provision of mixing device for supply of air-biogas mixture. The studies were conducted to assess the performance of modified CI engine on 100 percent biogas with particular emphasis on operational issues and efficiency of converted engine. Observation on suitability from ease of installation and operation as well as care and maintenance using both battery and magneto ignition system were also evaluated. The engine was operated with ignition timing of 250 BTDC. A long duration test of a converted CI engine coupled with an alternator (7.5 kVA) was conducted to evaluate the crank case oil quality when operating on 100 percent biogas. The performance of converted CI engine in respect of generator load, brake specific biogas consumption, thermal efficiency and emission of HC and NOX on biogas was evaluated. The fuel properties of biogas were also studied. The observed results of the experiment indicated that the CI engine converted to SI mode could develop maximum brake power of 4.5 kW on 100 percent biogas but at this output there was significant drop in engine speed. The drop in power is due to low heating value of biogas. It is therefore, suggested that the engine be operated at 1352 rpm developing 3 kW brake power for satisfactory operation of electrical devices through the coupled alternator and corresponding brake thermal efficiency was found to be 15.5 percent. The magneto ignition system found satisfactory for installation and operation than battery ignition system. The hydrocarbon and NOX emissions were observed lower on 100 percent biogas as compared to diesel and petrol. The long duration test of the converted engine on 100 percent biogas indicated no deterioration in crankcase oil quality however the engine should be operated for 500 hours for thorough evaluation of crankcase oil quality.
