wake up
SLV, ASLV, PSLV are all using Russian Engine. GSLV blowed up in 2010, GSLV III on the ground testing helped by Russian
ROFL Big Mouth Indians
Very first thing SLV, ASLV, PSLV didn't used or not using any Russian engine. These rockets used Vikas engine which are based on Viking series of European Rockets. It was France which helped India in developing these Rockets,not even Europe Space Agency. So get your doubts clear before vomiting crap theories. Russia did not provided help in SLV, ASLV, PSLV programs. It did helped in GSLV by providing cryogenic engine,even it didn't provided help in developing the engine itself. That should be enough for clearing your mind today.
So here you go.

Its vikas engine!!! The Vikas engine, based on the French Viking engine developed for Europe's Ariane launcher, is used in the Polar Satellite Launch Vehicle (PSLV) as well as the GSLV.
The ISRO has farmed out the manufacture of the engine to three Indian companies: Machine Tools Aids & Reconditioning of Hyderabad, Godrej and Kerala Hitech Industries Limited (Keltec) based in Thiruvananthapuram. The final assembly of the engines and the stages is, however, carried out by the ISRO. The PSLV requires only one Vikas engine (for its second stage). The GSLV, on the other hand, needs five such engines: one for each of the four strap-ons and one for the second stage. The second stage employs indigenously manufactured Vikas engine and carries 40 tonne of liquid propellant — Unsymmetrical Di-Methyl Hydrazine (UDMH) as fuel and Nitrogen tetroxide (N2O4) as oxidizer.
The Vikas Engine is a liquid fueled rocket engine made by India. It was developed by
Nambi Narayanan and his team during the 1970s.
It is similar to, the Viking.
The engine is used as the second stage of both the PSLV and the GSLV launch vehicles, with four strap-on boosters. The engine is also capable of swivelling.A up-graded version of the engine has a chamber pressure of 58.5 bar as compared to 52.5 bar in the older version.

An old news but never heard of it earlier.
Buoyed by its success in placing eight nanosatellites in prescribed orbits, the Indian Space Research Organisation (ISRO) is hoping to stage another feat by launching 100 nano-sats at one go. Scientists at the Vikram Sarabhai Space Centre, Thiruvananthapuram, are preparing elaborate drawings to make this event happen some two years from now.
The ISRO has already intimated universities world wide about the project and has extended an open invite to any varsity to take part in the historic venture. Within the country, the IITs in Kanpur and Mumbai were among the first to express interest along with ISRO’s Indian Institute of Space Science at Thiruvananthapuram. The Madurai Kamaraj University is already in the process of fabricating its satellite.
Can you tell me the name of that engine buddy used in SLV,ASLV,PSLV? Hmmmh that seems to be pretty much tough for you.
By the way PSLV has repeatedly proved its reliability and versatility by launching 53 satellites / spacecrafts ( 26 Indian and 27 Foreign Satellites) into a variety of orbits so far. More than indian ones. Way to go PSLV.
