The Olympic individual pursuit silver medalist took the winning time of 48 minutes and 35 seconds on Sunday.
It left her 22 seconds clear of Russian Olga Zabelinskaya.
Houvenaghel said: "It has been a real honour to compete here today and the support has been fantastic.
"As I focus on qualifying for the Games it is good to be able to come home and compete on home turf, especially as I have come away with a win."
The 22 mile event began at Stormont and took in Newtownards, Bangor, Holywood and Tillysburn.
The race was one of only four Olympic qualifiers in the time trials for London.
Incorporated into the Celtic Chrono event was a charity leisure cycle, raising money for Action Cancer, the NSPCC, Diabetes UK and Aware Defeat Depression.
