INVESTIGATIONS ON THE PERFORMANCE AND EXHAUST EMISSIONS OF A DIESEL: INTRODUCTION

INTRODUCTION

Madhuca Indica oil is an edible oil if suitably processed as per PFA rules. Madhuca indica is a botanical name of Mahua also known as Ippa in Telugu Mowrah in Hindi and Illuppai in Tamil, Butter tree in English. The Madhuca Indica oil is obtained from the seeds of Madhuca Indica trees of two major species namely Madhuca latifolia (Roxb) Mac bride and Madhuca longifolia (Ienig) Macbride; both belonging to the from Mac bride and Madhuca longifolia (Koenig) Macbride; both belonging to the from Sapotaceae. These two are so closely related that no distinction can be made in the trade of their seed or oil.

The tree grows up to 7- Ft and matures 8th year and yield fruits up to 60 years. The bark and root has medicinal value. The bank is also root has medicinal value. The bank is also useful for dyeing ant tanning. The corolla part of the flower is fleshy, thick and sweet and an important source of good source of fatty oil known in commerce as Mohwa butter Mohwa cake obtained after extraction of oil from seed is used as manure and as an insecticide. Fruit is a good source of fatty oil known in commerce as Mohwa butter. The oil is extensively used in the manufacture of soaps and lubricating greases and for edible purpose.

It is a large deciduous tree and grows in semi arid, tropical and sub-tropical areas, in altitude up to 1200m. It grows even on rocky, sandy, dry shallow soils and tolerates water logging conditions. Madhuca Indica longifolia grows only in South India.

Fruits mature and fall in April to July in North, August to September in South. They are fleshy, green berry, yellowish or orange brown when ripe.2.5 to 5 cm long; latifolia oblong and longifolia ovoid, contain 1 to 4 tiny seeds, the yield pr tree is 20 to 40 kg kernels.

The fallen are picked or felled by shaking of branches. The rind has to be removed by hand and seed is decorticated by beating with stones. The drying and decertification yield 70% kerned on the weight of seed. The oil content of kernel is about 46% in Latifolia and 52% in longleaf. The oil yields in an expeller are nearly 35%, 37%.
