CREATE TABLE table_12606 ("Engine" TEXT, "Capacity  ( l ) " FLOAT, "Power  ( hp ) " FLOAT, "Torque" TEXT, "Used" TEXT)

When was power (hp) less than 93 for the OM324 engine used?
SELECT "Used" FROM table_12606 WHERE "Power (hp)" < '93' AND "Engine" = 'om324'
SELECT "Used" FROM "table_12606" WHERE "Engine" = 'om324' AND "Power (hp)" < '93'
